have you checked for air leaks this could cause your problem,does it run ok once you accelerate or is it just on tick over i had a the same problem but cleaned out the ETM and that cured it

I ain't no mechanic but have come across this with an old car.

I've found its normally airflow related. If you've cleaned the throttle body then check the hoses or main air flow sensor, they're normally placed near the air fliter.
