Just out of curiosity, do me a favor and probe the voltage coming back to the computer from the coolant temperature sensor, both when cold and hot please. It might help me get a better picture if something's amiss.

Okay, I probed the voltage from the Coolant Temperature Sensor and got these numbers:

Engine Cold (KOEO): 5.0V
Engine Hot (KOEO): 2.8V
Engine Hot (KOER): 3.2V

I don't know why there's more voltage with the engine running.
Are these voltages within range?

Also, I uplugged the MAF and although the idle becames rough, it does not hang when I rev the engine. Is there a way to check the MAF?
Thanks again,
Phil
