THE PLOT THICKENS!
I just hooked up the gauges again on both low and high sides. With the car off, I was getting about 110 PSI at both. At idle, the low side bot down to about 80 and the high side to 140-150ish, but when revving it, they only got to about 60/180ish.
This is wierd, its like the compressor just isn't putting anything out or the expansion valve isn't providing resistance. The expansion valve is brand new, though. What gives? Should I take the freon out and clean and reinstall the old expansion valve (which is specifically labeled for R-134 - the new one isn't labeled either way)?
What would cause this?
