Hello everyone
I have myself a 94 s10 Blazer. The problem is every morning i start my car, it runs ruff (miss firing) smells like raw gas. When the engine finally warms up it runs fine and everything clears up.
It has a Glasspack muffler with the catalytic converter

I think it is the EGR valve or something. plz help

 

Could be dirty injectors (poppet nozzles) that are not atomizing the fuel properly when cold. Have you tried running some fuel injector cleaner through a few tanks of fuel?

 

yea nothing like that works
