Yes the CTS would make it run that rich if it was failing to provide the engine with the proper parameters.

I'll ask him that, but it only happens when the engine is ran for about 30-40mins and when it sits overnite It starts right up and rans OK. If it was an injector clogged or whatever I heard it wouldnt go away stays running rich.

Well marina called found out fuel pump in VST is only pushing 22psi should be @40psi Pump need to be change about 1K$ .
Does anyone know if VST needle sticking would cause that problem too???
