I AM HAVING A PROBLEM WITH MY AC COMPRESSOR CLUTCH IT KEEPS GOING ON AND OFF EVERY FEW SECONDS. I RAN A VAC AND RECHARGED THE AC AND IT STAYED RUNNING FOR ABOUT 2 HOURS THEN STARTED GOING ON AND OFF AGAIN. IT SEEMS TO WORK FINE IF I AM GIVING THE CAR A LITTLE GAS BUT AS SOON AS I TAKE MY FOOT OFF THE GAS IT STARTS GOING ON AND OFF AGAIN. THE AC IS COLD IT JUST DOESN'T RUN RITE AND MAKE MY CAR RUN LIKE CRAP WITH THE AC ON. PLEASE HELP ME LOL.

THANKS
CHRIS

ECM temporarily disables AC compressor during acceleration for more power so it ceasing when giving gas is normal.

I suggest you clean off and look into sight glass of the receiver/dryer to make sure you don't have contamination in system. A few other thoughts: Overcharge, too much oil, or bad Expansion Valve. Too much oil or incorrect pressures due to overcharge or bad EV would bog down compressor. It's common DIY mistake to use refrigerant with added oil when it's not needed. No oil needed unless parts in system are replaced.
