Hi Karl,

In your old post I suggested you clean the IAC, and obviously that didn't help... or did your symptoms change. Couldn't idle below 900?

Regarding the ECT, I believe you can break one that is old and brittle just by working in the area, bumping its connector, the stiff wiring harness, and so forth. The "in-ciruit" measurement in the FAQS is good because it checks both the voltage supplied by the ECU and the resistance of the sensor, but, yes you need to take the housing off of the ECU connector to probe the pins.

Best tool is a strong light -- at least that is the advice from an old presbyope. The pin numbers are molded into the connector body, though from memory (also old) I can't tell you which portion.

Remember the sensor or its wiring can be intermittent (broken) so that its failure may be temporarily hidden from your tests.
