    Hesitation upon acceleration...

    Hello! My trucks been doing this weird stumble when I press the gas pedal. It sounds like it wants to choke out and die but then it starts to accelerate. And just now I was trying to accelerate when not only did it stumble, but I heard what sounded like a back fire coming from the engine...

    New TPS= High Idle ?

    Im not sure where the throttle screw it. But I will double check that Im checking the blue and black. Im just following the connector since it has the letters A B and C on it. Oh and the iac only popped out when the motor was on. So im assuming thats no good?

    New TPS= High Idle ?

    Ok...UPDATE: The funniest thing occurred...I checked the IAC and observed the small tip pop out into the passage. But only when the engine was turned on. Not with just the key turned on. So hopefully that means its working right? As for the TPS, I started the truck and then I unscrewed the TPS...

    New TPS= High Idle ?

    New TPS= High Idle ?

    Im gonna try that soon as i get home. Although the tps fits right and snaps into the connector right, im starting to think they sold me the wrong one. But I'm gonna follow all these others steps as well if all else fails. Thanks for all your help.

    New TPS= High Idle ?

    Ok. In that case, i did adjust the tps then. I have the tps at full tilt counter clockwise. The lowest reading I got was about 1.15. Is it just a cheap tps or something? Perhaps they sold me the wrong one?

    New TPS= High Idle ?

    I've been doing a lot on my truck lately to get her ready for a little trip up the coast. I had the radiator pulled, new thermostat, new wires, plugs, new fuel injector connectors, etc. I also replaced the TPS and it's connector due to a small engine fire which melted the old TPS and connector...

    Smog Legal Headers w/ AC Delco Wires?

    :025: I'm at the end of my rope here, fellas. Ok I have an 87 Chevy 454 with smog legal headers. I really want to put AC Delco wires. Is it possible to do this? Would I have to buy each individual wire seperately, or is there a kit that comes with all 90 degree boots that would be compatible...

    Melted TPS and Connector!

    Hey Fellas! I have an 87 Chevy Dually 1 ton 454 TBI Dually. The TPS and connector which it snaps in to and mounted to the throttle body were melted. Someone was probably spraying too much starter fluid or something. Anyways, I'm trying to locate the connector which mounts directly to the...
