Reversed idle? 700 1990

SF-

I still have the same problem with my car after replacing the AMM. I was checking the FAQ's and there is a thread that stays the 89-90 700's have 3 temp sensors. one to work the gauge on the dash, and a second plug that houses 2 sensors, one of which sends info to the ECU. When this goes bad, the ECU thinks the engine is cold and dumps extra fuel, contributing to high idle, and possible like in my case, a rich mixure.
