All,
Let me start by saying that I know idle issues have already been discussed at length here. I’ve read all the threads and I’ve still got questions. In an attempt to fix the 3000 rpm idle at startup and hanging idle between shifts, etc., I have changed the IAC, TPS, cleaned the MAF, changed the PCV, and checked the EGR. I adjusted the throttle stop screw and got it to idle at 700 rpm with the IAC unplugged, but upon plugging the IAC in the idle went right back up even with copper cap restrictors put in the IAC inlet. The only suspect issue I can come up with are my TPS values. I am only getting .18V at idle and maxing out at 1.6V. Why would my TPS values be so far off? Even with Motorsport TPS? Gotta believe this is part of the problem. Any ideas?
