Anyone know what could be issue? im not sure what to look at. fuel pressure is fine, plugs wires are all fine. anyone ever had an issue like this to give me an idea what to look at? no engine light either.

its a 95 lt1 auto

 

Sounds like a clogged Cat!

 

Clogged cat would definitely be my first guess as well.

 

Thanks guys! Cat was clogged!!

 

glad that was the issue!!!
