hey guys, I've noticed one thing... I usually run with my a/c on 24/7. but, when I've had it off and turned it on (when the engine temp is low) it tends to shudder and the tach tends to fluctuate at lower revs. it happens too when I start the car with the a/c on and the engine is still pretty cold and I come to a slow stop.

is this normal? it's pretty damn noticable to me and my dealer says there's nothing wrong...
