Helppppp!!!, stumped with engine misfire code i cant resolve????
have an 2001 s60 with a P00303 engine misfire code. 3 times in past a replacement coil has always quickly and easily fixed the issue BUT NOT THIS TIME. Put a new EBay ( never an issue with them) coil and plug in cyl 3 and then rather than resolving my misfire issue pulled a P00304 which made no sense???????????. Before finalizing the coil bad I bought and put a new one in cyl 4 still getting a misfire????????????. With some uncertainty still about the replacement coil in #3 i swapped it with #1 and then pulled a P00300 ie multiple misfires????????????????. After some more swapping around i was relieved when the P00300 went away to become again the original P00303. So now with a new coil in 3 and 4 i swapped 3 and 4 and got a P00304 and AT THIS POINT I BECAME CONVINCED THE COIL BOUGHT FOR CYL 3 (before the swap) was BAD. So i go out and buy a much more expensive Bosch to replace coil in cylinder 4 ( the one originally bought for 3) fully expecting the 304 code to go away and misfire issue solved AND IT DIDNT---STILL WITH A 304 with new coils in 3 and 4 ( the bosch) and the original #3 new coil off the car??????????????. I AM TOTALLY STUMPED and dont want to take theis 2001 that i just want to pass emissions and sell to a shop and spend $$$-----------dont know what else they can do that i didnt--------------HELPPPPPPPPPPP ,ANY THOUGHTS????????.
