Buick Repair Questions? Ask a Mechanic for Answers ASAP
Hi Im David, if it was the alternator the battery light would be on and you wouldnt be able to keep re starting it.
you might want to pull of the IAC and EGR valve and clean them out with brake parts cleaner. they will have heavy carbon build up not allowing the air to pass trough as needed.
just checking in to see how its going
and what did they find, if i may ask?
