SOURCE: cylinder 3 misfire

Make sure you're using the recommended spark plugs. When my car did that, I had put Bosch Platinum Plus-4 plugs in and got that same problem. Turns out the plugs are too hot and cause it to fire prematurely and kick the misfire code.

Check your alternator see if you have a drop in voltage on your tack,then it is the problem.I too was a victim of high price tune up and still had a problem with a misfire.and cover your coil pack with a piece of rubber water run of onto your power pack .Another thing is to use a silicone spray on all wires.

SOURCE: Engine code states cylinder 2 misfire. Replaced

sounds like a bad injector, just connection at the injector, also check for leaks at intake, one more thing , do a compression test on that cylinder start there, good luck.

Misfire on Cylinder 3 swapped plugs between 3 and 4 on Pontiak Aztek 2003. Misfire remained on cylinder 3. Swapped ignition coil 3 and 6 with ignition coil 1 and 4 misfire still on cylinder 3


Try a new plug wire on cyl 3 if that doesn't fix it you could have a bad valve or compression problem on cyl 3 Try doing a compression test also If it has injectors for each cylinder you could have a bad injector for cylinder number 3

How to fix code P0306 cylinder 6 misfire?


Swap spark plug with cylinder 4. Swap COP (coil over plug) with cylinder 2.
If problem moves to cyl 4, bad spark plug.
If problem moves to cyl 2, bad COP.
If problem remains in cyl 6, suspect valve or piston problem.
Start with compression check

Cylinder 1 misfire


Have you tried clearing the code and go from there? Also maybe try unhooking the negative battery cable for awhile and that will reset it as well then see if it comes back to cylinder one. It's usually best to do all plugs and wires at the same time. Coils get expensive so I can see only replacing them when needed

P0306 and P0316


Okay, you were getting code P0306, and a P0316. You have replaced plugs and swapped coils around are you still getting the code P0306? or is it a different code for a different cylinder now? Replacing your crankshaft position sensor in this case will merely waste your money. Its doing its job, the P0316 is telling you you had a misfire in the first 1000 revolutions of your engine at startup, the P0306 is telling you its probably cylinder #6 that had the problem. there is no code there indicating your CKP is bad.

Now if you swapped your coils and the misfire is still on cylinder 6, its either injector problem, or base engine. If the misfire has moved to another cylinder, replace that COP.

Hope helps.

2003 mercedes Benz C240 codes P0300, P0301, P0302 and P0303. Please, help me how to fix?.


P0300 Random Misfire Detected
P0301 Cylinder 1 Misfire Detected

P 0304 Cylinder 4 Misfire Detected
P 0305 Cylinder 5 Misfire Detected
P 0306 Cylinder 6 Misfire Detected
You can Identify it's a faulty ignition system then next swap ignition lids from ignition coils be careful each coils have two lids one short and other long bit deference and when you remove and fix it to the car keep in mind correct order because each coil two different fire for two spark plugs don't mix up, if you mix it can create the fault code.if you detect any fault ignition coils or spark plugs or lids replace that and also whether god or bad recommend to replace spark plugs, find the right that's most important thing, if this way couldn't found the any ignition fault next step is check fuel presser, when the engine running fuel presser must be around 4.5 bar without engine running must be 4 to 6 bar if the fuel presser too low need to check two different things one is fuel pump other is fuel injectors, in this case you can swap injectors from right bank to left bank and find is the injectors leaking, if not leaking faulty fuel pump.is this information helped you? if yes please leave a comment,

Recurring #2 cylinder misfire.


Hello Mr Fixit...If memory serves me right, the PO352 B fault code would indicate #4 cylinder coil and PO352 A for #3. The
Possible causes ...faulty spark plug...faulty spark plug wire..faulty ignition coil pack..faulty PCM...open or short in wiring from PCM to iginition coil pack. To accurately troubleshoot and determine the problem you will need an oscilliscope and a diagnostic scanner. Without these you are basically guessing as to the cause.
The ignition control module is integrated into the PCM and a faulty ICM can definitely cause this trouble code...and i have seen my share of faulty PCM's.
Hope this helps and the best of luck to ya.
