That doesnt sound too hard. I just backprobe the two wire sensor with the engine off? What should the voltage be? Sorry for asking, but electrical stuff is something i haven't done yet.The idling should be opposite of that. Should be high on a cold start and slowly lower after 10 seconds or so. On warm starts, it will rev up slightly and come back down quick. First thing I'd check is a test on the Coolant Temp sensors. They're under the throttle body. I think the double-wire one is for the PCM, single-wire is for the gauge.
