Idel goes Up as the motor Warms up...????

[PKRWUD]

To check the IAC (IAB), unplug it while the engine is running. If the idle remains the same, there is a problem with either the valve, the wiring to the valve, or the passeges in the TB where it mounts. If the idle drops, the IAC is fine.

The TPS voltage has a tendancy to rise as the engine warms up. You said yours was at .084. That is way too low. Did you mean .84? Was this with the engine warmed up, or cold?

Try disconnecting the ECT sensor, and see if that makes a difference. If it runs better, replace it.

If you have a hand vacuum pump, try applying 15" of vacuum to your MAP sensor, and see if it holds the vacuum. If it doesn't stay at 15", replace the MAP sensor.

Take care,
