I have a 89 astro van that will idle great in park but when you put it into drive it wont hardly go. we have put on a new top part of the throttle body and new spark plugs and even had it put on a machine that didnt find any problems... in park it will idle great and you can even rev it up and its fine but when its in drive it just sputters and tries to die and even backfires in the throttle body. any help would be great and thanks in advance!!
