Two problems related to engine knocking noise have been reported for the 1998 Ford Windstar. The most recently reported issues are listed below.
While driving at any speed the vehicle stalls and the brakes grind. Had to be replace brakes twice and engine once. Consumer is hearing a banging noise coming from the vehicle and the vehicle will cut off without prior warning.
6 months after purchasing the van's problem with stalling out when stopping and then proceeding through intersections. It had been taken to the dealer once in roanoke (majic city Ford)_ and again in charlottesville, va with no problems found. The car comes to a complete stop with 'service engine soon" light and can't be started until put in park and then started. Also, as odd as it seems, it only occurs when turning 'left'. The air conditioning when started (max ac- ac- defrost settings) make a bang noise att the right front underside of the van. It occurs a few times in a row and then stops only to begin weeks later. The van has been brought into brady-bushey for this with no repair work performed because it did not happen when they tested it. They told me to bring it back when it happens again. But then, when it stops making the noise how am I suppose to prove this noise?.
