Check the fuel pressure: Vortech should be at the very least 55 to 60 PSI, Key on engine off.
TBI: Minimum of 12 PSI key on engine off.
Check the EGR valve, and the EGR ports for large chunks of carbon, if the valve is bad. Replace and use a Tomco/NAPA or Help products by Doorman, with the screen in it.
I hope this helps.
