2003 Ford F-150 Problems

Ignition Coil Failure Due to Excessive Spark Plug Gap

An illuminated Check Engine Light could indicate that one or more of the ignition coils has failed due to excessive spark plug gap. To fix this problem, the ignition coils that have failed, the spark plugs, and all coil boots should be replaced.

Noise from rear end when turning

If a noise from the rear end is heard when going around turns or after driving at highway speed for an extended period, there is an updated differential clutch kit available.

Engine Runs Rough at Idle

Intermittent rough idle may be caused by the EGR sensor sticking, causing the EGR valve to stay slightly open. The valve and sensor must be replaced together to correct this concern.

2003 Ford F-150 Recalls

Possible Corrosion of Fuel Tank Straps

Vehicles sold or currently registered in states using corrosive chemicals to de-ice the roads may have fuel tank straps that can rust prematurely and fail. If the fuel tank were to shift as a result of a broken strap, the fuel lines could separate or the fuel tank could contact the ground. In either case, a fuel leak could develop, increasing the risk of a fire. Dealers will replace the fuel tank straps with straps that have increased corrosion protection. Early in the campaign, if replacement straps are not available, dealers may install a cable support under the strap as an interim repair or a steel reinforcement over the existing strap as a permanent repair. This recall is expected to begin September 12, 2011. The Ford recall number is 11S21.
