Q: Car runs rough

asked by on February 19, 2016

My car is running rough.

The typical cause for many vehicles to start running rough is an out of tune ignition system. spark plugs are wear items that need to be maintained. The spark plugs receive the ignition spark from the coil pack which is a common failure item for your engine size. The coil pack can develop a crack or begin to perform poorly causing misfires. I would have a certified technician from YourMechanic determine why you are experiencing a rough engine. They will be able to diagnose your vehicle and perform the repairs to have your vehicle running smooth again.
