I've got a Redtop SR w/ stock t25 in my S13. I am having a problem with sputtering and stalling under boost, which eventually (20 mins later) turns into a bigger problem... my car running on 3 cylinders.

When I first crank my car up, it will idle and run correctly under light load. The first time I bring it into boost (10lbs), it bogs... but will hold the same boost level and continue to accelerate... although slowly.

Eventually... later in the drive, it will begin to run horribly, with CYL. # 3 not firing. When I pull that coilpack, I can hear it sparking, so... I dunno.

I don't have any boost leaks, my plugs are not fouled, and the car is not blowing any smoke or burning any oil. All my grounds look good, and the MAF is connect properly... but it hasn't been checked with another one (z32 unit.)


HELP ME. adrian

Pull the coil pack and look for cracks even hairline cracks.
Had a crack in mine and it got bad when the temp
rised and did exactly as you described. I know you
chacked spark but it might be grounding to the head if you have a
crack.
