Engine was not running properly. Took vehicle to dealer, and they stated that head gasket needed to be replaced. Please provide any further information.
Motor pings under load in overdrive when using a/c at 40-45 mph. Requires taking out of overdrive manually. Dealer reports no codes upon computer check. Engine also pings in winter on load going up grade at 40-45 mph in overdrive. Dealer reported engine computer indicates very lean condition when forst purchased. . . . No correction available. Mileage excellent 20-21 around town and 27-30 on highway. This is a great van except for the pinging. Have tried mid range and premium fuel and premium with no better results. My research show a spark knock sensor is present. . . . Is it supposed to sense this problem and correct timing or is there another possible fix?.
