That is a much clearer description...thankyou. My Ford has two temp sensors. One is for the gauge. The other is for the computer to tell it what the coolant temp is. If THAT one goes out the computer is confused and keeps the engine in a too rich condition.
I cannot remember if your engine has two of them or not. I doubt an oxy sensor would cause this problem from low temp.
Someone else on here will have a better answer..perhaps.
