QUICK! Digifant 2 HELP!

[jlagnese at massed.net (John S. Lagnese)]

You can also check the idle and WOT switches. They are on the throttle body.
There is a test at the computer connector for this. I don't have my Bentley
in front of me. LMK if you need the test. But the blue sensor is the piece
to change. The test on that is open or high resistance cold and closed at
temperature.
