Well, when the oil pressure does get close to zero at a stop light...etc. I can hear a slight knocking noise coming from the motor. So that kinda tells me that the gauge is right and the oil pressure is sinking too low.....my opinion only. I thought about adjusting the idle speed up a tad, but on a TBI, I really dont know if you can with the computer, sensors and all.
Thank you Marsal420, all help is greatly appriciated.......you too 2000CAYukon.
