Hello. If the misfires are continuing to occur and the ignition parts are good then it may be a faulty fuel injector or an issue within the engine. I usually do a compression test first. By doing this I would know if the problem was internal such as a valve seat failure. If the compression test comes back fine then I test the injectors on those cylinder to make sure that are fine. If those happen to be good also then there is more than likely a problem within the circuit that is causing this and further diagnosis will need to be dine. If you need to have this misfire fixed, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose and repair this.
How to Identify and Fix Common car Problems ?

The P0302 error code indicates that cylinder two is misfiring and not receiving enough spark to its spark plug.
Chrysler P0300 indicates that two or more cylinders are experiencing misfires.
The P0300 engine code indicates a misfiring cylinder problem in your vehicle. The misfiring happens when insufficient fuel is burned or when the spark plug gets damaged.
The majority of the time, a misfire is caused by a faulty spark plug or another problem with the spark system, but it may also be due to: A fuel delivery problem. A mechanical engine failure. Exhaust gas recirculating.
What the P0203 code means. The P0203 is a diagnostic trouble code that is set when the engine control module (ECM) has detected a fault in the injector circuit for cylinder 3.
The most common and relevant cause of a P0300 code is spark plugs that are damaged or worn. This is also a common cause among additional codes displayed as P030X. Spark plugs are devices that ignite the compressed mixture of air and fuel in each cylinder of an internal combustion engine.
Various factors, including defective spark plugs and insufficient engine compression, can cause misfires.
A blinking Check Engine Light indicates a more serious misfiring problem. The P0302 trouble code is an indication that cylinder 2 is misfiring and is not getting the necessary spark to its spark plug.
To find the cause of a misfire, start with checking for trouble codes in the onboard diagnostics system with a scan tool. The codes may not pinpoint a specific part, but they should identify the cylinder or cylinders that are misfiring as well as other systems that aren`t functioning properly.
If it varies beyond 2 percent, the Monitor will set a P0302 code and illuminate the Check Engine Light. If there is more than a 10 percent variance, the Check Engine Light will blink or pulse in a steady manner to indicate that a harmful Catalytic Converter misfire is occurring.
P0200 is a diagnostic trouble code (DTC) for “Injector Circuit Malfunction”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
The code is usually located on the injector head. DENSO Common Rail injectors – generally all require coding, although some very early versions may not. A typical code length is 16-24 alphanumeric characters depending on the vehicle make. The code is usually found on the injector connector.
Yes. While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
There are a few things that can cause this such as a dirty fuel filter, or a worn-out fuel pump. It`s easier to diagnose than a vacuum leak, so many mechanics start here.
Diagnostic Trouble Code P0300 can set if you have faulty spark plugs, low compression, damage or excessive wear of spark plug wires and/or coils, faulty fuel injectors, clogged EGR valves or tubes, burned valves, improper ignition timing, vacuum leaks, leaking head gasket, faulty camshaft sensor, faulty crankshaft …
The catalytic converter may certainly cause the P0300 random misfire code to show up due to the inability for the exhaust to properly breathe, which can cause un-burnt exhaust gases to reignite inside the catalytic converter. A clogged or failing catalytic converter can cause the vehicle to have poor fuel economy.
The P0301 code means that cylinder 1 has a misfire and isn`t burning fuel properly. Bearing in mind that you need air, fuel and spark for combustion, the cause of a P0301 code could come from a few different sources. In any event, a P0301 code is serious and shouldn`t be put off.
Worn or fouled spark plugs are one of the most common causes of engine misfires. These small but crucial components deliver the spark that ignites the fuel in your engine. If they`re not working properly, your engine won`t be firing on all cylinders.
All input and output engine management devices (i.e., sensors, ignition coil packs, etc.) are connected via electrical circuits. Problems within these circuits, such as damaged wiring or a loose connection, can cause engine misfires.
Misfires don`t simply go away – they need to be addressed immediately. Even if they don`t get worse, they certainly won`t get any better unless you take the car to a mechanic.
Any raw fuel in the catalytic converters quickly overheats them and leads to their destruction. If misfires occur severely then damage occurs quickly. If misfires are subtle, then damage may not occur for a year or two.
If left untreated, a cylinder misfire can lead to significant engine damage. Worse, if you experience a bad misfire while driving, it could result in an accident. This is why it`s important to treat engine misfires as soon as you detect them.
A common emissions code seen in the field, a P0420 trouble code indicates that the catalytic converter isn`t functioning efficiently.
