My 2004 GMC Yukon oil pressure drops whenever I
slow down & occasionally cuts completely off if I'm
on a hill or come to an abrupt stop. What is
causing this to happen?
do you know when the last service was, change the oil and filter, as oil ages it thins meaning the pump can not pressurize it correctly and if you run it like that you'll certainly blow the motor, my advice to you is to take your automobile to your local shop and a qualified technician should be able to diagnose the malfunctioning oil pressure
Try to flush the oil very good. Normally price is $100. If it is not gonna help. It is might be an oil pump or internal engine problem. But we did fixed with flush many chevy tahoe oil change problems.
