I have a question regarding my 2003 Suburban. It seems to idle rough here in PHX with the AC on, the engine starts to shake a little and feels like it is going to die. Without AC on it runs fine, I also noticed some buzzing and occasional flapping noises when running about 20-30 MPH when the AC is on. At other speeds it seems fine and these noises do not occur when the AC is off.
I think it is about time for a tune up so maybe this will help with the rough idling? Can anyone shed some light on this for me?
