Hi i have a 2002 chevy cavalier 2.2l 4 cyl. My ac works fine when coasting and idleing, as soon as you press the accelerator at all it blows out warm air. If i have the car on cruise control at any speed/engine rpm it blows warm.
Along with lurching on accelerating from a stop, in 1st gear by the time the engine rpm is reaches 3000 the engine rpms would rise and stop rise and stop approx 3 times. I figured this would occur because the car only has 120 hp and the ac draws alot of power, however the ac not working while cruise control is on is confusing. Any suggestions??

 

sounds like a vacuum leak

 

check engine light on? The a/c is designed to cut out at throttle positions over 80% which the pcm considers wide open throttle. Check and see if there is a tps sensor code or any dtc for that matter.

 

The check engine light isnt on, and when the ac is off the car performs as it should without any hiccups

 

Is the cooling fan on with a/c on?
