I just changed the fuel pump and TPS and the truck is running a hell of a lot better, but when i take off and when im at top gear, it periodicaly sputters as if it has air in the gas line. I've already changed the EGR, TPS, plugs, rotor, cap, fuel filter, and fuel pump, also, i've gutted my Cad. Converter. When I hit the throtle, it runs just great, what the hell is the deal? Someone told me that my TPS needed to be calibrated or that I need new plug wires. I dont think the plug wires would do that but what do I know. Please help.
