AnswerYour most likely very common fault is the normal buildup of a BLACKISH STICKY RESIDUE buildup around the throttle plate area.
gain access to the throttle plate by removing the fresh air intake hose(s) and clean the throttle plate area with a spray cleaner available at most any auto parts store. just ASK one of the counter people for help in selecting a product.
You may need to clean this area 2 or 3 times and on a regular basis as necessary.
