2002 Other Cadillac Models HESITATION IN IDLE

Try cleaning out the idle air control valve

will do...ill get back when i do

i had the air idle control valve cleaned out and that didnt work. ive done that, checked through computer and it says everything is fine. engine jerks in idle and hard to accelerate. way more intensified with a/c on. kind of like a hesitation jerk. been to numerous mechanics and no one can put their finger on the problem. please let me know if you can think of anything else..thanks for the time!

Check the crankshaft position sensors and the throttle position sensor/MAF/MAP sensors too-

If numerous mechanics, and the vehicles own system do not detect a problem, is it safe to say that it is normal operation? Do the other mechanics feel what you are trying to describe, or does the concern not occur in their presence? Is it possible that the fault lies with the air conditioning, something like overcharge, or liquid slugging? What is your history on owning the vehicle, have you just aquired it, and feel there is a problem?

ive had it for a yr and a half. it didnt do it before and ive brought it to a cadillac dealer. i thought about the a/c and something electric but who knows. i do know its not normal! everything i get from you im relaying over to my mechanic so i appreciate this!!
