Hey folks! It's been a long time, but I'm back with a problem..
My wife's 01' 4.0 runs and idles fantastic, except when the HVAC is turned to anything (but) floor only or vent only. With those on it's just fine. When I turn it to AC, floor/vent and defrost, it will idle really low like 500RPMS and the AC compressor will kick on, and it almost dies, then back to 500 ad so-on. It will do this every few seconds. I saw another thread about something similar here on the forums, but I think this might be different.
I checked very thoroughly for vacuum leaks and pulled the IAC off and cleaned it out. It didn't seem too dirty, and all the vac lines are in good shape and connected properly. The truck is not throwing any codes. Any ideas what's going on here?
Thanks in advance
Chris
