Are you buying cheap crappie gas?

IT'S NOT the knock sensors, they should last 80,000 miles easy, if it was the same shop every time they are ripping you off. a trouble code is not the problem, its where you start diagnosing. Lot of miles? if the engine is getting noisey the knock sensors will (hear) ticking / rattling, same way they hear preignition (spark knock), and tell the PCM to retard the timing = poor mileage
