the car starts up fine and then lopes real bad and then it dies it has been doing this ever sense we put a new tranny on it

when we do get it to run ok it runs good for about 10 min theN the idle goes krazy and the vacume gauge is going back to 5 or 10

this isnt a iacv problem its something else WHAT COULD THIS BE

SOUNDS LIKE ITS MISSING BUT I HAVE SPARK AND FUEL ALSO WE TRYED a DIFF DIZZY


no vacume leaks

 

hello

 

how do you know you have no leaks? It sounds like vacuum to me. A good way to test this is to get a can of starting fluid and judiciously spray a bit here and there in your engine compartment with the engine running. If it very temporarily revs up quite a bit, you've found a leak.

 

because its holding 20psi no problem
