Alright, 265K 97 ODY, timing belt replaced 6k ago. Oil light comes on flashing first at idle after a good 20 mi drive. No rough idle, no more new noises like not enough oil on moving parts. Then in park after flashing oil light, a solid light. Checked oil and its full, with clear fluid and new filter two weeks ago. I thought kicking up the RPMs would get rid of the light but to no avail. Also, if its related, when turning on the A/C, at idle the motor is loud, but quiets when disengaged. Hmmm and wanting to get this resolved. Where is the oil pump located? Is there such a thing as an oil pressure sensor? if so can I change it out? Thanks.
