One problem related to gasoline engine has been reported for the 1996 Ford Aerostar. The most recently reported issues are listed below.
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?.
