Has had a new IAC put on it twice since January. It has a new TPS, just installed last week. No vacuum leaks that I can find. I cleaned throttle body and I re-coated the throttle body walls because I heard the cleaner was bad for them. It has a new MAF that was put on in February. The problem was there before all of this was done. It started about a month ago...... Cold start, it will take 3 or 4 cranks to get it to stay running, then when I come to a stop light it will want to hang idle at 2,000 RPMs. Sometimes 2,500. I haven't messed with the idle screw. I'm out of options. Has anyone had this problem and fixed it? Does anyone know what it could be?
