2003 Mitsubishi Challenger Pricing and Specs

The eyebrow height is measured from the centre of the wheel, vertically to the edge of the wheel arch. The vehicle needs to be on flat ground and unladen for this measurement to be taken. In the case of a 2014 Challenger, the standard front eyebrow height is 542mm and the rear eyebrow height is 552mm.

A fuel blockage is definitely one possibility. When was the last time the fuel filter was changed? But in the case of the earlier, petrol-powered Challenger, don’t disregard other things such as an ignition problem which could involve spark plugs, ignition leads or some component of the distributor or coil(s). Has the vehicle sat idle for any length of time? Modern fuel goes `off’ pretty quickly and poor or rough running is a classic symptom of that phenomenon.

If your car is the later diesel version, the same comments regarding the fuel filter apply, but the situation is magnified as the fuel systems on these modern, common-rail turbo-diesels are quite complex and run at enormous injection pressures. Sorting out a rough running problem in one of these Later Challengers is best done by first electronically scanning the vehicle to see if its on-board computer throws up any fault codes. Those messages can then be decoded and you’ll have a much better idea of what’s wrong. Frankly, the problem could be anything form a high-pressure pump failing to a throttle-position sensor sending false information back to the computer.

If the engine runs when you apply some throttle but won’t idle, I’d be drawn to the idle stepper-motor which is a small electronic actuator that is designed to keep the engine at a stable, steady idle when no throttle is applied. It’s a pretty simple fix, but I’d also check things such as fuel delivery pressure and ensure that the ignition system is in good condition, also. Don’t forget air and fuel filters, either, they’re simple things but critical to how an engine behaves. Low battery voltage can also make an engine like the Challenger’s play up at idle, too. Also, have the throttle-position sensor checked. If this fails, it can leave the computer guessing about what the accelerator pedal is trying to tell it.
