Ok guys, definately need some help on this one. Just put in a freshly rebuilt engine and now when I turn on the AC the compressor turns on for 3-4 seconds and shuts off for 4-5 seconds and over and over again. And when it turns on it sounds very irregular, too much pressure. If I'm in gear (any gear, this is a manual trans) and turn it on it puts a heavy heavy strain on the motor, as if I'm slappin the brake hard and stompin on the gas (compressor turning on & off). Today I checked the running pressure and when the compressor was on it was at 140lbs! When it shut off it dropped to 120 or so. I shut the AC completely off and checked it and it was at 200+lbs! Is this a clogged orphice? Please let me know, I live in SoCal and its about 110 daily. Thanks for the help.
