my denali oil pressure has read way over 80 and then the today it started to act up. when at idle it is high and as soon as i hit the throttle it will drop to 0 let off and it goes back up again. any one ever came across this problem before.............i have not yet varified the actual oil pressure but I doubt its bad since it only has 120000miles and the oil has been changed regulary
