Is my pump going bad? When in gear and brake depressed if idle drops below 800 my oil guage goes back left to red line and beyond! If I put it back into neutral and get to idle at 800 (roughly, bounces between 750 and 800) my oil pressure goes back to normal (between the N and O in normal). Does it sound like i'm having idle issues or just a pump going bad? The bronc doesn't die but the needle tries to swing farther left than its possible to do..like its cavitating or something :scratchhe. Any and all comments appriciated.
