Q: Q: Car shaking while idling.

asked by on

It shakes a little while idling.

If the engine shakes a little while driving this could be a fuel or ignition systems malfunction. If not enough fuel is being delivered to each cylinder or if the ignition system is not strong enough to burn the correct amount of fuel, the engine may shake and seem unbalanced. I would enlist the assistance of a YourMechanic technician to check your vehicle for trouble codes with an OBD2 scanner. Once trouble codes are found (if any) the diagnosis can continue. The likely cause of this issue would be a misfire due to a fouled spark plug or ignition coil but be sure to have both fuel and ignition systems checked thoroughly.
