Smoking from the exhaust after it warms up
My 94 chevy 1500 runs great until it warms up
then it smokes and loses power? It doesn’t smell
like antifreeze but more like burnt gas I changed
the plugs and they were really loaded with carbon?
The motor was changed in it they put headers on it
and there is a plug on the exhaust that’s not plugs
in to any thing?
Do a compression test
