2000 blazer 4.3 2 wheel drive auto trans ...........anyone ever seen this problem?
idle haywire when you turn on AC, idle jumps up 500 to 1500 rpms
had it at 2 shops, it doesnt want to mess up when it goes to the shop
have had the smoke test done, replaced ivac , tps ,temp sensor, mass air flow,
first time it went to the shop, they told me the intake gasket was bad had that fixed
shows no codes? now as soon you turn the ac on 80% of the time it will act up.
and even if you turn it back off it still acts up for along time.
ive done some research but cant find my problem, ive read that the reveits on the Throttle Body get loose but mine are fine, the mech from the shop said it could be the ECM?
thanks guys <<<<<<<<<<
