My car will randomly idle rough at low rpms and run rough under acceleration. It will typically die when stopping. If it happens, it’s when the engine is hot and been running for at least 15 minutes in highway driving. Frequently, it will occur while driving and then return to normal. Whenever this happens, the “service engine soon” light will come on and then turn off. I have not had it happen at a time or place when I can check the engine codes, so I’m not sure where to start in diagnosing.
