Question about 2002 Cadillac Escalade Ext
Truck has been running rough, changed fuel filter,spark plugs, air filter. Shifting rough, stays in passing gear longer than it should. Also can hear pinging noise when pedal is pressed completely down. Surges back and forth, and loss of power especially when accelerating. This is driving me crazy, the only trouble code is misfire and multiple misfire. Check engine light does come on, but then mysteriously disappears. Also tried running higher grade fuel with no luck. Need some advice please
My truck did the same thing. turn out it was a Max Air Flow sensor. cost for part is 350.
