I'm running down this problem myself. It's intermittent, and I think it's the root of my 18mpg instead of the low 20's I should be getting.
I cleared the ECM after changing plugs, wires, and air filter. 2 months later, I still have problems with high idle. Last weekend I was going 40mph from a dead stop without ever touching the gas pedal. Put that puppy in neutral and it went to 3 grand on the tach and stayed there.
This weekend, my plans are:
Clean Throttle Body
Check and Clean Throttle Position Sensor
If that doesn't work, I'm going to replace the forward O2 sensor.
