I just checked and found a sensor broken under the spark plug wire cross over plastic bracket / chanel. I thick it is the temp sensor but not sure. It is just to the left and on the front of the intake manifold. It is a green 2 wire plug and the wires are red with blue stripe and a brown wire. Yes the car runs just fine after it warms up.
As for back ground we had the intake manifold gaskets change and shortly after this problem started. I was out of the country so I did not over see the work done. Guess if you want things done rite you got to do it your self.
So if this is the coolant temp sensor why does the dash gauage show temp to run ok?
I will order the sensor and post the results here. Let me know if this is a temp sensor or what you think it may be.
Thanks so much for your help.
