Hey all,
I seem to be having a misfire issue when I am cruising 75+ mph. The issue is almost non-existent in the early morning when I am on my way to work (6 AM) except when I am almost there (I drive an hour and 15 mins each way), but on my way back to work, it is horrible, it can barely go 75 without surging.
I scanned and it appears that all the misfires are on cylinders 2 and 5. So naturally I thought coil pack; swapped coil pack, did nothing. I am thinking maybe the ICM is next?
Also, when I get up to that speed, the LTFTs are way out, around 11.6+. I replaced fuel filter and injector o-rings and it helped around the city with the LTFTs, but the highway characteristics of the car haven't changed. Don't know if that is related or not.
From what I know, it has new plugs and wires. I will shotgun those next if the ICM doesn't fix it. Any suggestions?
