Fire it up at night in the dark and look for arcing. It may be arcing throught he plug wire, it may be finding an carbon path to ground on the plug exterior, or on the coil pack.

Also- check the wire terminal connections for corrosion and make sure they snap into place. on plug and on coil pack.

#3 cylinder is misfiring ?


check ignition coils. you can swap with another cylinder coils and see if misfire changes to other cylinder. If it jumps to other cylinder where there you atached the coil from cylinder #3, change the coil.
You can also check Coil On Plug Boot for damage and simple change the part. very easy and cheap.

Number 3 and 4 are not firing from coil on 2002 subaru outback 2.5


its faulty coil.

Get the compression test done on each coil.these will let you know if its faulty coil or not.

=========

It can be issue with spark plugs or faulty spark plugs. Also get the compression test done for cylinders. If any of cylinder shows low compression then required, then that particular cylinder will cause misfire.

Also get obd codes scanned, the error code will let you know which cylinder is misfiring or all cylinders are misfiring.

Cylinder 3 misfire


head gasket blown or warped heador cracked head on engine

1 Answer

Missing intermittenly, shows problem with #2 cylinder. Could it be the coil and can you purchase separate coils.


Theses coils are separate, but handle 2 cylinders at a time. So in your vehicle you should have 3 coils.Random misfire may be caused by the following: due 4 tune-up, faulty coil, faulty spark plug, faulty plug wire, faulty cam or crank sensor, poor cylinder compression, intake/head gasket leaks. Before replacing parts, make sure that #2 cylinder is diagnosed for the misfire. Otherwise you'll be changing out good parts, and spending more $$$!!

I have a 2002 TrailBlazer with the straight 6,diognostic check said #3 cylinder was dead or misfiring, also map sensor showed up. #3 cylinder was misfiring, so to test the coil pack I swapped #3 coil pack...


did you replace only one spark plug? that can cause issues because of differences in resistances between cylinders. also, did the map code stay off after replacing
?

Cylinder Misfires


It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind
