Hi there. When a car is slow to accelerate it can be caused by multiple issues, ranging from fuel systems that are clogged or damaged to an ignition system component failure. It is also possible that something in the driveline system is dragging which causes the lack of acceleration. Since there are so many different possible issues, the best way to start the diagnosis process is to have a professional mobile mechanic from our team come to your location and complete a car is slow to accelerate inspection.

How to Identify and Fix Common car Problems ?

An indication that a vehicle is not receiving the right mixture of air and fuel is if the vehicle jerks or surges forward at high speed. Several components of the fuel or air intake system could cause this jerking or surging sensation to happen. Issues within these systems can also cause fuel economy to worsen.
Clogged Fuel Filter: The job of the fuel filter is to filter out containments in the fuel and if it becomes clogged it can restrict the amount of fuel that reaches the injectors. This can cause a vehicle to accelerate slowly. Fuel filters are designed to be replaced on a regular basis.
(Nissan) is recalling certain 2007-2011 Versa Sedan and 2007-2012 Versa Hatchback vehicles. The affected vehicles have a driver frontal air bag inflator that may rupture due to propellant degradation occurring after long-term exposure to moderate absolute humidity, temperatures, and temperature cycling.
Fuel economy for the Nissan Versa Hatchback is 7.9 L/100km City and 6.3 L/100km Highway (while equipped with the 6-speed manual transmission), 8.5 L/100km City and 6.2 L/100km Highway (while equipped with the 4-speed automatic transmission), and 7.3 L/100km City and 5.8 L/100km Highway (when equipped with the CVT …
What could the problem be? There are a range of reasons why your car is juddering when you accelerate. Your vehicle could have dirty fuel injectors, a damaged fuel pump, a blocked catalytic converter, a faulty mass airflow sensor, broken spark plugs, or even an accumulation of moisture.
Clogged Fuel Injectors

A clogged fuel injector can prevent the fuel your car needs to accelerate, thus causing you car to jerk in the process. If you hear your car engine stuttering, then the injectors may not be providing an adequate amount of fuel. To fix this, you should clean the injectors on a regular basis.

There are a few reasons why your car might hesitate when you press the gas pedal. It could be due to a problem with the mass air flow sensor, the oxygen sensor, the TPS, or the fuel filter. It could also be due to a clogged or dirty air filter.
There are a number of different things that can cause a car to have sluggish acceleration. Some common causes include a dirty fuel filter, a bad throttle position sensor, or a problem with the oxygen sensor. The timing belt may also be worn out, preventing the engine from accelerating properly.
Is the 2010 Nissan Versa a Good Used Car? Yes, 2010 is a good year for the Versa getting an average overall rating of 7/10. Owner reviews praise the fuel economy, comfortable cabin, and the relatively low ownership costs. Interior materials are good for an economy car with an average interior quality score of 7/10 .
What qualifies as fuel efficient, then? Anything that is listed as less than 6-litres/100km or more than 16.5km/1-litre is considered to be pretty good. The first (and most common) reference is litres per 100km (litres/100km). This is how many litres of fuel the car needs in order to travel 100km.
The 2021 Nissan Versa has a 10.8-gallon fuel tank on all of the trim levels. It comes standard-equipped with a CVT transmission and gets an EPA-estimated a combined 35 miles per gallon, due to 32 miles per gallon city, and 40mpg on the highway.
Worn Out Spark Plugs

This means that your spark plugs are not igniting the fuel in each piston cylinder in a timely manner, causing your car to jerk around while accelerating. If your spark plugs are worn out they should just be replaced, as they are generally an easy and inexpensive repair.

Hi There, The jerking reaction you are describing may indicate a dirty or failing mass air flow sensor which is a unit that monitors air intake and relays this info to the ECM which then makes adjustments to the fuel supply. This could also possibly be related to intermittent fuel pressure or an ignition problem.
Typically, a surging or jerking motion can be caused by an unbalance of air and fuel in the engine. Your engine needs the exact amount of an air and fuel mixture to properly perform the combustion process.
Many different faults can cause the vehicle to jerk and have acceleration issue. The most likely cause of these are spark plugs, battery, alternator, fuel pump, low transmission fluid, MAF sensor, vacuum leak, exhaust leak or oxygen sensor. All of these would need to be ruled out before the transmission was replaced.
Typically when the car will not accelerate past 60 MPH, it`s due to either the ECU activating a limp mode or other mechanical (fuel or ignition system component) failures.
Loud squeaking or squealing noise while accelerating could mean there`s a problem with your engine belt. It could mean the belt`s loose or worn. Or it could mean that one of the belt`s pulleys is starting to fail. Loud rumbling noise when accelerating might suggest there`s a problem with your exhaust system.
Dirty fuel injectors are among the most common reasons for why an accelerator becomes jerky. The dirty injector leads to your car losing power when you attempt to accelerate while at a stop and when you try to drive at a consistent speed. This is the result of an engine misfire.
Check engine compression and intake vacuum to first rule out possible mechanical problems such as stuck or leaking valves. Among the causes of poor acceleration are clogged fuel injectors and/or inadequate fuel pressure/volume.
Rough starts, hesitation and poor acceleration are all common symptoms of a bad spark plug. If a spark plug or multiple spark plugs are faulty, they will have trouble creating the spark that causes the ignition process in your vehicle.
In government crash tests, the Versa scored four out of five stars for all occupants in both front- and side-impact tests. The Insurance Institute for Highway Safety gave the Versa its highest rating of “Good” in the frontal-offset and side-impact crash tests.
Four transmissions are offered – a 5-speed manual (Sedan 1.6 Base), 6-speed manual (Sedan 1.6, Sedan 1.8 S, Hatchback 1.8 S), an electronically controlled automatic with overdrive (optional Sedan 1.6, Sedan, 1.8 S, Hatchback 1.8 S), and Xtronic CVT™ transmission (Hatchback 1.8 SL only).
The All-New Nissan Versa gets incredible gas mileage at up to 32 city and 40 highway MPG with the Xtronic Continuously Variable Transmission. With a full 10.8-gallon tank of gas, the Nissan Versa is able to tackle up to around 345.6 miles of city driving or up to 432 miles of highway driving at best.
The National Highway Traffic Safety Administration (NHTSA) gave the 2023 Versa five out of five stars overall, and the Insurance Institute for Highway Safety (IIHS) gave the small Nissan sedan the highest-possible Good ratings for moderate-overlap frontal impacts and side impacts.

ANSWER : Hello, thank you for writing in. If the new battery has also failed to hold a charge, the alternator is likely not working correctly. You can test the alternator at home with a voltmeter, or you can remove it and have it tested at most automotive parts stores. It will need to be replaced if it has failed. You will also want to make sure all of the electrical connections are clean, dry, and tight. For more help testing or replacing the alternator, contact our service department to schedule an appointment.

Shifting from 2nd to 3rd, car stopped going fast. Now it won’t go at all.
ANSWER : It is possible that your clutch has failed. The sound you are hearing is likely due to the clutch not engaging with the engine due to it being worn. I would recommened having your transmission inspected by a qualified transmission expert to determine if your clutch requires replacement in order to resolve this issue. This inspection may require removal and partial disassembly of the transmission in order to verify that the clutch has failed.

ANSWER : Hello, thank you for writing in. Your vehicle should not be experiencing any major issues at this point, but that will be determined after an inspection as issues can happen. Your owner’s manual is the best source for letting you know what the manufacture recommends for a 100,000 mile tune-up. It will likely include the spark plugs, oil and filter change, air filter change, and a full inspection of all brakes, suspension, and major engine components. This may also be a transmission issue, and you may want to have your transmission fluid and filter changed as well. For more help, contact our service department to schedule an appointment.

i put 91 super in my car and is says use 87 premium now my battery light is on. what is going on? 2009 Kia Sportage
ANSWER : Hello – you did nothing harmful. Your car may have a small level of performance improvement for this tank of fuel, but nothing extraordinary. Long term use of fuel with a higher octane level, MAY lead to increased levels of unburned additives in the exhaust and catalytic converter, but we’re talking about 10s of thousands of miles here for any "damage". The engine simply burns the premium fuel as-is, and doesn’t really use the additional anti-knock additives in the fuel. No harm, no foul. The battery light may be a slipping or broken serpentine belt, a failing alternator, or voltage regulator. I recommend a charging system inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, and give you an accurate assessment of damage and cost estimate for repairs.

I bought a vacuum cleaner and attached it to my car while my car was ignited, I used the vacuum cleaner and the battery died
ANSWER : Hello and thank you for your question. It seems that the battery in your vehicle has a low charge and probably has an overcharged cell. I recommend replacing your battery then re-testing to see if it keeps on starting up. As far as trying to start the vehicle like a manual, on an automatic transmission, that will not work for the transmission will have not oil pressure to the clutch packs. The engine must be running to create the oil pressure to make the clutch packs inside the transmission work. If you need assistance with your battery, I recommend seeking out a professional, preferably one from YourMechanic to help you with your vehicle.

Battery and oil light come on when trying to start car, take keys out try again car starts no problem and lights go away
ANSWER : Of course, don’t switch gears without being fully stopped, unless your Owner’s Manual or the manufacturer has alternative advice. However, the gear shift issue has no relation to the no-start problem you are describing. Inasmuch as you only have 6,000 miles on the car, the "constant on and off" that you believe has occurred is meaningless in comparison to the expected total vehicle service life. That is, assume what you perceive as "constant on and off", during merely 6,000 miles, might be equivalent to using the car "normally" for three years. A new car should be trouble free for at least 5 years, unless there is a defect, so your "constant on and off" is not a causal factor for any fault on the vehicle. What you might have is a defect in the ignition switch, or perhaps the immobilizer system, but if the problem is not in the switch itself, clearly there is an electrical problem.

If your vehicle is under warranty, by law the dealer MUST repair the issue you are describing within a prescribed time frame and number of "attempts", otherwise the dealer will run afoul of Federal and state Lemon Laws that give you very specific rights, and recourse (contact an Attorney; we are Mechanics, NOT attorneys). Consequently, if the vehicle is still under warranty, to save yourself money do be sure to seek a resolution from the dealer. If the vehicle is not under warranty, obviously a certified Mechanic from YourMechanic could identify the electrical fault and resolve this for you. If you want to go that route, please simply request a no start diagnostic -electrical system and the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
