The car would speed up by itself from fault of throttle control assembly, alternator had to be replaced, windshield wiper hose assembly, the ac compressor had to be completely replaced, accumulator or receiver drier had to be replaced, as well as replacement of the compressor drive belt, evaporator orifice belt, serpentine belt tensioner, idler pulley, belt tensioner, on another recent occasion, the Ford was idling high and when driving, would speed up to around 4000 to 4500 rpms, on its own replacement of gasket all spark plugs, valve assembly, and another kit 11794 to counter the revving engine and throttle. . Also the power steering was off in the car,and it could not maintain an alignment, as you drove the steering wheel would jerk and shake. Odd noises emanating from the left and right rear of the car resembling a wheel bearing also will probably result in further repairs. The work was done at mileage 85462. Today it is 102k and the Ford keeps up with its seeming reputation of being "found on road dead". . . Or "fix or repair daily". Today completed by a Ford dealer and a military shop, the torque converter is broken. The car will start and rev, but when placed in drive or reverse it will not engage and remains in place.
My 2005 Ford Taurus seems to have a mysterious problem that two dealerships and my mechanic cannot recreate. The problem does not occur on a regular basis. The problem is when the brake pedal is depressed, the abs light and check brake signal flashes, and then the engine light comes on, the battery light comes on and the car stalls. . . Stops dead in its track. If does not happen on a cold start only after the car has been running during the day. I took it to one Ford dealership and they replaced engine intake value. That seemed to work for about 1 year. One year to the day, it starts again. The next Ford dealership had it for about 5 days and could not re-create the problem. However, they replace the air intake valve, spark plugs and a new belt. The problem occurred 5 days later but much worse. The car stalled 4 times in one trip. The following day, it worked on the cold start and 4 hours later, it stalled twice going 1500 feet. There is something wrong with the car no one can fix it. The diagnostic test machine shows no error.
