Reader Question: Austin,
I have a 2004 Pontiac Grand Prix. Have you heard about or if you know anything about an idling or fading out problem when starting the engine of the Grand Prix. I was reading some reviews and seem several comments were in that area and I seem to have that problem also.
Any information about that would be helpful. I do not get the impression it is a correctable problem.
Most erratic idle, slower and extended starting, and dying at idle or slow speeds complaints are usually caused by a dirty throttle body and idle control motor. You can have your mechanic, or even a fast lube place clean both items for you inexpensively and quickly.
This service should be part of your regular routine maintenance program anyway regardless of it correcting this specific problem or not.
