2003 Ford Mustang Problems
RepairPal has identified the most common problems with the 2003 Ford Mustang based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The synchronizer shaft for the camshaft position sensor can cause a loud squeak or chirping noise due to failure of the upper bushing. The noise may be erratic and is usually present when the engine is warm.
If a squeaking noise is heard while turning the steering wheel, the outer tie rod ends may be worn and should be replaced.
A creak/pop noise while turning may mean that updated steering rack bushing tubes need to be installed.
If you experience difficulty starting the engine when cold, stalling at idle, or hesitations during acceleration, it may be the idle air bypass valve. This valve helps the vehicle idle steady when the accelerator pedal is not pressed.
The magnet for the camshaft position sensor may fall out of its mount and damage the synchronizers. This causes long crank times when starting the engine and may cause the Check Engine Light to illuminate. If this happens, both the magnets and the synchronizers need to be replaced.
