 Subject: erratic idle/ TPS adjustment
IP: Logged
Message:
I did the TPS adjustment app. 2-3 weeks ago, and now have a problem. I reset the PCM after the adjustment, and everything was fine for a few days, then this problem occurred. The truck has an erratic idle. Sometimes it idles normal (around 600-700 rpm), and other times it will idle around 1500-1700 rpm. It also idles back and forth throughout this rpm range sometimes as well. Also, when the truck is in Drive and the idle is normal (600-700 rpm), and you shift it into Neutral the rpm's become erratic and go up to the 1500-1700 range again. Is the TPS adjusted to far, or is something else going on? Any help would be appreciated.
P.S. I also did the map sensor mod about a week before the TPS mod. Could this be the problem. I have checked for codes, and there your none. I have reset the PCM app. 3 times, and it still did not fix this problem.
