The jerking is more likely to be engine related. The fact that the check engine light is on means that trouble codes, likely related to the issue, have been stored and are available for downloading. Those codes will provide important clues that aid in a diagnostic. Your issue can be diagnosed and resolved if you request an engine diagnostic. During such a diagnostic, the certified mechanic would come to your location and run through all the possible causes of engine misoperation, jerking in your case, and those possibilities include exhaust manifold leaks, worn seals or gaskets in the exhaust system, a failing catalytic converter causing exhaust blockages, malfunctioning oxygen sensors, dirty fuel injectors, fuel pump malfunction, faulty spark plugs, a faulty mass airflow sensor and vacuum leaks.
