Default Stalling lopey or lopy surging idle when ac is on
I can take it for a five mile cruise with ac on and stop and start with no problems. It's when I turn off ac and back on again engine will raise rpm a little the drop to normal and then stall.car does have a mild cam so lopy idle may be the cam?
So what about the stalling?Idle air valve maybe?

clean the iac reset timing and check your rpm at idle
