I would check the injectors
So i changed my clutch the other day.......
Removing the flywheel, 6 triple square bolts came out.. four remained, stripped. How did I get them out? I used an arc welder, welded bolts to the stripped ones to turn them out. Did not remove ground terminal from battery. Stupid I know because chances are that might have caused my issue.
What I know now; I relpaced the cam, crank, and speed sensor. Swapped coilpack with a known good one. Checked the harness for breaks in the wires. Understanding how a coilpack works, this gets strange, cylinders 2 4 6 have a weak spark or none at all when I hold the plug to the head and 1 3 5 have a strong spark. What may have been shorted that could have caused this? I hear mentions of ICM and ECU, i'm not familiar of the ICMs location or function because it seems if 1 gets a strong spark, how does 6 get a weak spark, they share a bank in the coilpack.
Ive aleady swapped spark plugs and wires to see if the problem would travel, nothing.
Thank you for the ICM clarification. So it's part of the coil pack assembly, well that's been replaced with no change in performance. Still crap.
crank looks for a gap (missing teeth on the gear it reads), You most likely cooked your ecu.
Check the resistances on your injectors.
