I did an Idle learn on my tune after the HC swap. I thought it idled a little high when in gear (about 575rpm) so I disconnected the PCM and Batt and tried again (not thinking the IAC controlls this duh) Now I get a ses light before it will learn the idle, and its the TPS code. I would think the IAC was the culprit?? I can reset it and it will stay off a while, but it wont learn the idle. When its cold it starts fine, and after you get it to idle its fine, but if you start it warm its a PITA to keep it running for about 30 sec- 1 min. Is there any way to check the TPS and/or IAC. Or other opinions?? I dont have any scanning equipment, but a bud has a predator for checking codes. Thanks
