Engine Mechanical problem
2003 GMC Sierra V8 Two Wheel Drive Automatic 100000 miles
took vehicle in due to oil pressure signal, replaced oil
pressure sensor. Signal came back after about a week. Was suggested to replace oil pump, then told engine had sludge. Regular oil changes were done on vehicle. Do you have any suggestions as to problem?
Signal seems to come on only after highway driving.
have the same problem?
