TPS Sensor

Anyone have a flat prong TPS for a 95? Possibly used?

I got a round plug and spliced the wires over the weekend, but its running rich and stumbling at idle.

how do you know that's the problem?

I'm not sure how the TPS would cause those type of issues.

Sounds more like an idle air control valve symptom so worth checking that, too.

I was throwing a code with the old one. Engine would feel like it was cutting off when driving for a split second. I replaced the TPS with one off a Range Rover that Brian K (Brewie212) dropped by. Spliced the wires, cleared the code and the symptoms while driving went away. The old TPS (flat plug) and the newer one (Round plug) have different gauge wires so I dont know if it is a resistance issue or if I just need the correct part.

It idled fine with the old TPS, just didn't drive very well when accelerating.

This part is reasonably new. I cleaned it to be safe.

resistance change would be constant ... and the gauge of wire will make no difference.

Have you measure the resistance on the bench and see if you have a clean sweep? its easier with a meter with a dial indicator rather than lcd display.

see page 73 to measure voltage when on the vehicle

I have an entire intake, throttle body, sensors, iac valve and all. Cheap.

Ill box it and mail it off if that helps. Shipping costs and some beer money and its yours. Or I can rob the sensors and mail just those.

I am sure I have exactly what you are looking for, but the round plug TPS from a 95 RRC sure aint it.

That is why im in search of the flat/square plug. I figured it couldnt hurt to try the wire them together. Going against kindergarten teachings of fitting square in round hole.

It kinda works. Isn't throwing the code anymore. Just doesn't run all that great either.
