View Full Version : For those with high idle and warm start issues

Thought I would pass this along. It might help some.

Its a long story, but I ran into issues of high idle followed by the dreaded "starts cold OK, but will not start warm"

After hours of trouble shooting, incl changing the TFI, the fuel pump and more, I found it.

Check to make sure the spring in your TPS (and mine was brand new) is not broken. That's all it was. I would set it at .9v, and still the problem persisted, until I decide to check it a gain after I had started the car and found the voltage at 4.7v !!

Took it out, sure enought the spring to return the TPS to idle was not doing its job. Put back my old TPS and set it, all is fine.
