It is 4 cylinder and just shuts off while driving

Hello, sorry you're having these troubles. The check engine light being on indicates there is one or more diagnostic trouble code stored in the engine's processor that will possibly shed some light on what area to start troubleshooting in. A trained technician at a shop near you can dig into this concern and get to the root cause of it. The check engine light may not be related to the idling and stalling though -- some concerns do not set the warning light on and do not set diagnostic trouble codes. Another reason hands on testing by a skilled technician is invaluable. Go to this link, enter your information and find a shop near you to contact! www.repairpal.com/repair-shops
