Welcome to CamaroZ28.com!

"New Member Intro" isn't the best place to get tech help. I'll move this to "LT1 Based Engine Tech" for you.

Probably need to provide a bit more info:

-how many miles on the engine?
-manual or auto trans?
-stock or modified engine?
-if modified, what are the engine mods?
-does it start easilly?
-when does it run poorly - at cold start, when fully warmed up, both?
-do you know if the Optispark distributor has ever been replaced?
-have you scanned it for codes?
-have you checked the fuel pressure?
