Check the connector on that cylinder,if it is ok,then the driver for this injector,or coil is most likely bad,this is in the computer,but first check all vacuum lines,especially near that cylinder.

misfires are more often from a blocked/faulty injector rather than electronic
pull the injector and clean or replace
check for injector operation and wires

Replaced #5 coil and all plugs on 06 jeep liberty vehilce still shows misfire on #5 cylinder after clearing all codes


it sounds like it could be number 5 injector. I suggest you swap number 5 injector with one of the others and see if your misfire moves to this cylinder

Cylinders 1 and 2 are misfiring causing major vibration and engine shut off while idling...is this a fuel injector problem?


This could be an ignition coil, spark plug, fuel injector or mechanical problem. You will need to isolate the issues and proceed accordingly. I would do some swapping arround. Swap the spark plugs 1 and 2 with m# and four and see if the misfire follows if it does you need plugs do the same with the coils again if the probles switches cylinders replace coils. if not then you may have to llok at injectors, compression and so on but I would try swapping things first

Misfire on cylinder # 5


5.4 Liter? If so you should have a coil on plug ignition. Pull the number 5 coil and check for spark. If there is no spark swap it with number 1. If there us still no spark than replace the coil.

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
P0302 Cylinder 2 Misfire Detected
P0303 Cylinder 3 Misfire Detected
according to this fault codes first mark ignition coils
3 ---------------- 6
2 ---------------- 5
1 ---------------- 4
RB-------------LB
this right banks and left bank, please remove Ignition coils with lids and spark plugs from right bank and swap with left bank, if fault code change as
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,

I've a problem with misfiring in # 5 cylinder -combustion failure


1. Swap two ignition coils between #5 cylinder and another one.
2. If the #5 cylinder misfire problem is still present you must check up wire by wire the electrical supply cable from the Engine Control Module (ECM) to the #5 ignition coil. Repair damaged wire(s). The last piece out of order will be the ECM !
3. Inspect also #5 spark plug if it is wet or dry. If it is dry then you must verify the #5 injector!

2006 dodge caravan, 6 cyl. relaced cole, sparkepugs and wires in oct. 2009. Engine is reading #2 cyl. misfire again. Why


Firts time swap spark plug & ignition coil between two different cylinders and read again if the same #2 cyl. misfires !
If #2 cyl. is OK and another cyl. misfires then spark plug or ignition coil is out of order and must be replaced.
If #2 cyl. misfires again then #2 injector must be checked !
If ignition coils & spark plugs (complete set for 6 cyl.) are replaced then you must check #2 injector !
