These symptoms could have numerous causes. The first step is to retrieve the diagnostic trouble code (DTC) associated with the Check Engine Light. This code provides a starting point for the diagnostic procedure. There is a technical service bulletin (TSB) I found that might be related to your issue. The TSB is number 10-21-6, and it states an unstable idle and Check Engine Light may be caused by a faulty throttle body. It also says that replacing your throttle body is the remedy. A trained mechanic, such as one from YourMechanic, will be able to inspect your vehicle’s vibrating issue and tell you if this repair applies to your vehicle.
