I was driving home approx 1 week ago, and I got into the throtte hard. As always the oil pressure went above 100psi. But after returning to an idle I noticed the gauge was still reading over 100psi. I drove like that for approx 30 min the rest of the way home, and when I restarted the car everything was normal again. Well, last night I was driving home again, and approx 1 hour into my drive i noticed the oil pressure gauge was dead. I countinued to drive the rest of my trip without problems (approx 30 more min). I noticed that the little red oil pressure light WAS NOT on, but when I got home I restarted the car, and the light worked at first satart up. Does the car have two diffrent oil pressure sensors? one for the red light and one for the gauge? or is my gauge bad? Has anyone else experienced a gauge/or sensor falure on the 355?
