A/C not working - need help I did some mod to the car, including a FAST Intake and a LS2 t/b.
When I turn the air cond. on the light blinks until you keep the rpm's
up. When the throttle position drops below 12% the computer shuts off the a/c. I checked the coolant with gauges and everything seems ok. Is there a something in the computer ( a setting) that I am missing .When the rpm's are up, a/c is cold and the engine idles smooth. As soon as you let off the gas and it goes to idle the a/c constantly goes off and on. The idle is set at 975.
Any suggestions and help will be appreciated

you may need to add some freon to the system. maybe a half a pound of 134-A
If the compressor keeps kicking on and off when at idle the computer has not shut off the a/c. It just maybe low on freon. My buick does this, soon as I add some freon to it, the compressor will kick off eventually but will remain on all the time.

You need to adjust the idle tables with A/C on. On the tune file you have one for in gear with a/c and in gear no a/c. Then you have park no a/c and park with a/c. I bet it needs to be worked out a little bit.
