oil pressure dropping up and down in Tahoe
recently purchased 95 Tahoe when idleing oil gauge shows about 20
then give it gas to go an drope down to 0 but no knocking and check
gauge light comes on but when I get to 30 mph it shoots up to 40 and
depending on speed it will stay from 40 to 60 but still dance a little.
When I come to a stop same thing will happen again. Replaced the pressure switch and did not fix it. I have heard that it could be the screen in the pump getting clogged can someone give me some direction to go. Oh the truck only has 114,000 miles on it. thanks
