Re: power loss and check light
OK cLEANED THE THROTTLE BODY, EFI chamber, and intake manifold, replaced all with new gaskets. Found that I had the Cold start wire in the wrong place in the ECM wiring block. Truck starts but wants to die after about 30 sec. of running and hesitates when throttle is opened, also has power loss when going up hills. Found the EGR valve was bad changed it, made no differance, tested the ECM and all VSV valves and switches all good. I'm running out of ideas going to check the fuel pressure and the converter. What do any of you think my problem could be.
