Whatever the mechanism is for adjusting idle when the AC compressor is engaged is not working. When engaged, the idle is dangerously low and will occasionally cause the car to die altogether when letting off the accelerator.
There is no obvious mechanism I can see for this so I assume that the computer controls it. Any ideas what I can look for? Just had the dealer look at it and
500 bucks later there is no change.I can find two different screws that adjust the overall idle, but to get a decent idle speed with those having the AC on I just end up with too high of an idle when the AC is off.
TIA
