Re: 1990 Chevy Lumina Accelerates Slowly Dies in reverse

The crack in the exhaust isn't helping. May be screwing with the O2 sensor by letting air into the manifold.

Other parts of your symptoms sound like a plugged catalytic converter.

You need a scan tool for real diagnosis, and also a restriction test of the exhaust. What is the fuel pressure?

Ten trillion to start with, increasing as needed from there, PLUS compensation for the sickened, and "wrongful death" settlements for the families of those who didn't survive. END trade with Communist China.
