this is at idle and only after the motor is at running temp. i have changed the oil to see if maybe the oil was thinning out and no good. i put valvoline Max life 15w40 in it so i know its not thinnning out now and its still doing it. mechanical gauge says it at 35 to 40 psi at idle. and about 60 from 1500 and up even when running down the road. i also am having and issue with the clutch so im wondering if im slowing the idle down to the point the computer things it going to stall.
