LS1 sputter
Aight folks: 1998 trans am, LS1, 148K miles, still factory errthing.
It has been sputtering for sometime now. It is getting worse in that now idling is rough and when you turn the a/c on it really gets bad (driveable but very noticable). I've took all the injectors out and clean them and the rails with Seafoam, fuel pressure is real good. Even rigged up the pressure gauge so that I could see it while driving and it stays on 58psi. This weekend I am going to Seafoam the intake, change the plugs and wires to MSD and NGK, change the oil too ofcourse unless anybody has any other suggestions. Thanks

I suggest going to the NAPA store and get a can of CRC MAF cleaner and clean the MAF.
you might want to clean your IAT sensor also. Its the little one located on your 98s lid.
