I have a 94 Silverado 1500.. 5.7L and it will not go over 30 mph... I can mash on the gas and it will not pick up speed... When the trans shifts and I mash on it... It still will not go?? I'm stuck.. I dnt kno if it'* a trans problem.. Catalytic converter prob.. Or fuel prob..

Check engine light?

Nope check engine light not on

Well it popped on for a sec. Then went off..

Check for codes. And BTW, starting multiple threads about the same thing is typically frowned upon in the car forum industry.

Well I didn't know how to delete it or edit it.. Oh well..

From my description.. Any ideas what it could be??

Nope. We could play guessing games all day long as to what it could be. Check for codes and get back to us.

My guess is you have a restriction in your exhaust system. A pinched pipe, plugged cat, or something like that. Like Mike stated, getting it scanned for codes would help us to narrow it down.


My father in law had the same problem with his car. He brought it over to me on a Saturday morning, and before he sat down for a coffee with my wife I came in to tell him it was fixed. I never did tell him his downturned exhaust pipe had caught a curb and bent back until it was kinked. I bent the exhaust tip back into place and the problem was fixed. I just let him think it was due to my superior mechanical wizardry, and the legend lived on. Your symptoms are exactly what he was experiencing.

Agree....typical cat symptom is, if you lay into it from a dead start, it tops off at 3K rpms, and won't even shift......if from a dead start you feather it, it will slowly shift and get up to speed.....usually sets a P0420....
