After 30 miles had to remove the 1, 4 coil and put the not so bad old one back this was because it was miss firing really bad with p0303. So I had a new coil and an old one. Drove it for 900 miles then today it started to miss fire again but only in gear, low rpm and when opening the throttle still no check engine light
Did I messed up the ICM by installing the AC delco d5555?
The old coils messure 7500 ohms
The new ones messure 5700 ohms
This happens mostly in closed loop.
have the same problem?
