A/C Compressor Cycling 95 w. manual climate control
I'm having a problem with the A/C on my 1995 88. Bought the car recently and have been busy sorting out other problems (UIM, master cylinder, etc...) and finally got around to this. The A/C compressor cycles every 5-20 seconds when the A/C is on. The car has the manual climate control (twist *****) I thought it might be low on freon, so I evacuated the system and pulled out 2 pounds, which is what the underhood sticker calls for. The system held a vacuum for 15 minutes, so I went ahead and refilled the system. 2# and it still cycles. The A/C blows as cold as any car I've owned, and I don't get any blasts of warm air. I even added a couple additional ounces to see if that might trigger the compressor to stay on, but no luck.
Any ideas what might be going on. It must be a hefty compressor, because I really feel the engine lag when it kicks on. It'* actally pretty annoying -- under acceleration it feels like the car is surging when the a/c is on.
Car has 57k miles.
Thanks in advance
