Others and myself are having good luck with the Autozone sensor.

I stated in my first post that I was getting 10 MPG before AND after changing the ECT sensor. i never blamed low mileage on the ECT sensor. I just stated I even changed it and i was getting same results, in addition to the high rpm problem that i got AFTER I changed the sensor.

and thanks I will see if I can get my mechanic to check the fuel pressure regulator out
