So my PFC has decided to no longer cut the injectors under decel below 4K rpm or so, which makes the revs drop very slowly. I am trying to figure out what would have caused this. It seemed to coincinde with me changing some values trying to smooth out my idle, but I changed the values back, so I don't think it is related. Could this be caused by the TPS being out of adjustment? My voltage for VTA2 in idle position seem pretty high. Around 1.8 volts. Stock should be .8 or so, however, after looking through my logs I see that the voltage has always been this high. Any insite as to what tells the PFC to cut fuel? I assume it gets its info from the TPS.

From memory I believe the furthest out vta2 should be is 1.25. Why not write down your current specs for reference and calibrate it? If there's a negative effect or worse you can always go back. Whats your idle currently doing?

I have been having high idle issues as well. I seemed to be able to fix it for a short time, but when this started happening the revs never even make thier way down to 1400, which is where I want it to idle.
