The >>Running pressures<< are correct?
1. Do you have r134? Tehre may be a High pressure cutout on the liquid line.
2. You may have a bad TPS or TPS wiring which would show an intermittent WOT,
but that shows in driveability too.
sounds like the IAC to me.. its suppose to keep the rpm's up when the
a/c is on and its not doing its job and that is why the alt. is not
putting out enough juice as its going slower and thus you get the
compressor cutting off via the pcm control on the relay...
hope this helps.
The IAC is exactly what appears to have been the problem. I
swapped it out this AM and put on a couple hundred miles
around town today with no problem. The IAC checks out to be
good and was not dirty as I had expected. It still looks
like that was the culprit.
