High idle and no Check Engine light.

[RIDE THE]

Heres some free advise that you didn't ask for.


If for some reason you get a high idle and no check engine light present on your SVTF, run the codes and see if you get code P1121 or P1124 in memory in the PCM.

If you do see those codes change out your TP sensor. I ordered a sensor and thought that I could drive the car with a high idle for another day until the sensor came in and the sucker shut off and would not refire.

Just an FYI that I thought might save somebody else a long walk or a tow bill. It was a pretty long walk back to work for me.

Or you can clean your TB and tune.... might solve it too.

Not when the TP sensor is reading 3.45 volts (or part throttle) at idle. The sensor is separate form the throttle plate so cleaning the throttle body would do nothing to the sensor to change the reading. Once the sensor was replaced it fired right up on the first attempt.
