Crazy TPS problem! Please help!
I know there are a million TPS threads but I havent found anyone with my problem.
1990, 5.0, 5 speed
Surging idle, no codes
TPS voltage:
Green wire, 4.99V
Black wire, 4.99V
Doesnt change with throttle position
Has anyone run accross this before? Thanks.

the black is the ground side iirc..if you have voltage on tha side there is a short somewhere on that side

I put pins in both the green and black wires. First checked the voltage accross the two and it was zero (gunna go back tonight and check resistance between the two to see if they are shorted together). Grounding my black probe to the battery and probing with the red lead, the green wire and black wire both showed 4.99V.

You should have a fault code with what you are describing. Are you sure you pulled codes correctly?
