Good Morning Paul and thanks for responding to my post. I'm actually researching a rich idle condition. My mechanic had mentioned that there possible could be an issue with the coolant temperature sensor. Apparently, he explained that the sensor feeds a signal to the ECU which in turn affects fuel delivery if not working correctly.

I ordered a temp sensor from PP's; however, I haven't been able to locate anything on the car that looks similar....I've found the Thermo Time Switch.

The temp sensor that I purchased has 2 leads so I don't believe this is for the gauge. My gauge works perfectly....

I've also noticed that the Economy gauge, at idle, is about 1/3 the distance from the far left. I'm assuming at idle, it should be pegged all the way to the left...

One last point. I've changed the dizi cap and rotor, got new plugs; however, the number 8 cylinder is not firing. If I pull the plug wire,there is no change in the engine....

Thanks again for the response.

Best Regards,

Todd
