This thread has been a very interesting read, however, I think the problem I am experiencing is a little different.
When I turn My AC on, it gets cold ok, but it seems to put the car into limp mode or something. I narrowed it down by chance to the AC.
The car runs fine until you turn on the AC. It starts to misfire. Sometimes almost straight away, sometimes it may be 5 or 10 mins later.
No lights or warnings come up, just no power and a car that feels like its running on 5cyl.
Just today I thought I would try it and as soon as the engine revved over 2500 or so, I would get a terrible rattle out of the compressor. So it sounds like my compressor is shot, but I dont want to spend $1000 replacing that to find it still goes into limp mode.
Sorry if its a little thread jacking.
Ben.
