    Ok here it goes. I just recently put in some new injectors in my cobra. It pretty much was an easy task. now im having issues with TPS, IAC, EGR position sensor, Temp sending unit. A buddy of mine hooked up a scanner to it. from what it said there was a bad ground somewhere. well i was referred to this tech at a local dealership. He says there was a ground wire somewhere on the upper or lower intake manifold. and it has broken when manifold is removed. he says its there. ive never heard of such a thing nor can i find it. well my buddy grabed his volt meter and says there was no ground to the IAC, temp etc... ya i dont know. so if anyone has any advice or has had this problem i would appriciate it.
    Thanks in advance.

    Check that all the harness connections are tight.

  4. look at a wiring diagram and find the splice for the grounds, sounds like you have a splice that got corroded or a ground thats loose.
