Bought the 45 dollar ECT - replaced it and no dice, but in the process, I located a vacuum leak so that is probably it. This EGR Pressure Sensor ???
Has 2 mounting bolts to the upper intake - 1 bolt is missing. I recall replacing them both when I did the upper intake gasket, but the lower mounting bolt is missing now, must not have tightened it up properly.... sigh.
Damn it Jim - I'm a geek not a mechanic! lol
Will take the other bolt out and see if I can find a match for it at lowes or something. Will update thread with result. In the meantime I blew out the low beam on a headlight and got that replaced, and still need to figure out how all 4 blinkers are no longer operable, gotta be a fuse under the dash....
