Car jerked and engine light turned on

Hello, I am Danny.

Well, first and foremost we are going to need to know what the check engine light (codes) are to diagnose your vehicle. If you do not have a diagnostic scanner/code reader you can go to your local auto parts store (Pep Boys, AutoZone,O'Reilly's) and they will usually check them for free. Please be sure to copy/write down the codes and information and we will be happy to help! I have attached a tutorial to give you an idea of the scanner/diagnostic code process. Hope this helps and feel free to ask any questions if needed.

Personally, I would start with checking the battery cables and terminals. Loose cables can cause all sorts of weird problems. In particular, you want to make sure that they are extra clean and that the terminals are tight enough that you cannot move them with your hands.
