On three separate occasions the vehicle has stalled while driving on the highway. Each time this happened the vehicle could not be restarted and had to be towed to the nearest garage. The dealer informed the consumer that service bulletin 12950 as issued in 1999 identifying a fix for this problem. Since the consumer's vehicle was no longer under warranty he was forced to pay for the repair.

While driving vehicle stalled. Consumer used a starter battery kit to restart the vehicle or contacted aaa to have the vehicle towed. The aaa representative indicated that the stalling may be due to engine motor failure. Dealership and sears retail store performed a diagnostic test, but no failure code was found. Also, the battery and air bag warning light came on. This failure almost caused rear end collision. Owner is an ex philadelphia Eagle football player named curtis bunch-black.

Ltr fm louis hettinger(ky) owner of a 1998 Mercury Grand Marquis 4-door vehicle question if vehicle should be recalled because of fast idle. The iac valve was replaced on the vehicle but did not help the problem. The service dealer stated that there was nothing else they could do to resolve the issue. There were other consumers who experienced the same problem. (there was a fast idle upon start up and the vehicle would slow down at short notice. When the problem occurred, there was no way to control the vehicle)
