Bob - It is more than likely a bad sending unit. I damaged mine during an oil filter change, and it "pegs" with the engine running. I know that my pressures are correct. There are several replacement senders that are advertised as being "more accurate" than the original sender. Most vendors have them available. The sending unit for the gauge is next to the oil filter. The sending unit for the idiot light is on the opposite side, just behind the A/C compressor. If the idiot light is functional, it *should* show a real problem if you have one.

The car has 18000 original miles and I have changed the oil regularly. When I first got the car I warmed it up then changed the oil. Then I ran it 100 miles and changed it again. It seems to be flowing through the engine alright but it worries me. Could it just be a bad sensor? Bob >
