Fellow members,
I need help or advise, here's what my issues and current repairs are;
my 03 GT will not idle under load or when a/c is turned on. when a/c is turned on and at idle it will idle erratically. I can drive it without a/c all day long with no issues but once a/c is turned on it goes to crap. will not idle at stops, will not stay running at idle, runs erratically. Turn a/c off and it takes a few minutes to reset itself. so here are the specs and some of the attempted fixes;
total engine rebuilt 1 1/2 ago, Comp Cam extreme energy stage 1 cams installed.
car ran good until 1 month ago, no issues.
4.6L automatic
changed IAC solenoid
Changed MAF, MAP and TPS
Cleaned purge solenoid located inside of passenger side front fender.
checked all vacuum connections, no issues.
installed a air/oil separator.
Cold air intake
had a mechanic dial in TPS and reflashed ECU. Mechanic could not find issue.
have performance chip installed by BAMA tunes. I have it set to factory setting right now.
please help. KLB
