Will the temperature controller for a 93' S10 blazer cause to much fuel to be sent to the engine? My vehicle seems like it is miss firing but it smells like it is running rich. In idle it is fine but when driving it seems to be miss firing. All cylinders have been tested and are good. All new plugs, wires, roter, cap, O2 sensor(1), fuel relay, fuel filter, spider injection system, right side head gasket, and both valve cover seals. I have a the new temperature controller that will help with my guage working. But I am at a loss. I don't know what to do from here. PLEASE HELP.

Have you tested fuel pressure & leak down rate?
