2019 ford Explorer

Hello, I’m Pete from the Car Genius team at RepairPal. I’m sorry you’re dealing with this concern on your Ford Explorer. A rough idle at a stop light can be caused by numerous different components or reasons ranging from a misfire due to a worn spark plug, faulty ignition coil, faulty spark plug wire, injector, or even an internal engine concern. This rough idle can also be caused by carbon build up inside the throttle body, worn or damaged engine mounts, bent or damaged exhaust components, among several other possible causes. If any warning lights are on with this concern this also lets you know that the computer systems have detected an issue with one of the engine, transmission, or emissions related components and has stored a fault code for this concern to aid with locating the fault. The best thing to do would be to have your vehicle properly diagnosed by a reputable repair facility to identify the cause for this concern so it can then be repaired properly from there. This helps remove the guess work and long hours spent trying to identify the concern yourself.
