I really need a scan tool bad
Not having a laptop sucks too.
Car is doing something similar to when I first installed the smaller SC pulley.
Acceleration is strong but if I accelerate from a dead stop....even without any wheelspin...and hold it at full throttle, after about 13 secs. when it gets to almost exactly 90 mph it stops accelerating and feels like I lifted the throttle to half even though it'* still matted, then accelerates very slowly. Knock retard can't be that dramatic, can it?
If I start full throttle acceleration from a higher speed, it doesn't happen.
Sort of kills my 0-100 or 1/4 mi runs.
.....even with a cool engine and outside temps.
Like I said, it did that when I first installed the pulley a couple of years ago but went away after a short while.
Is this a PCM learning thing.....or maybe associated with the new DPH computer
The higher fuel pressures or the AFC 1.1 didn't help.
