I posted over in the thread Pucci opened about relocating the aux air valve some info on an MUCH MUCH easier location to measure the ECM temp sensor... check it out...

I measured mine this evening after driving home from work. Engine DEFINITELY up to temp in this heat/humidity! I was reading 248 ohms. Last night when the engine was cooler (but not "stone" cold, still probably 90 to 100 degrees) I was reading 1.25 Kohms, so it seems the sensor is not my problem. I also did the test with the AAV that Pucci outlined, and I don't believe that's the problem either.

I'm leaning toward a crudded up throttle body, or dirty injectors... I'm planning on pulling the TB this weekend when I adjust the valves and re-torque the bolts on my new head and cleaning it out real good...

C/YA!
