Q: Vehicle sputtering

asked by on

My vehicle is sputtering and not accelerating like it should.

You most likely have an engine misfire. The cause could be an ignition coil, spark plug, or plug boot problem, such as the valve cover leaking oil into the spark plug hole, shorting the coil out. I recommend that you have a mechanic, like the ones from YourMechanic, come by and to scan your car’s computer and diagnose the cause of your vehicle’s sputtering.
