Q: Truck idling roughly.

asked by on

My truck is idling roughly. When you come to a stop, the truck wants to stall.

A rough idle is usually caused by a misfire in your engine. This is usually caused by a problem with the spark plugs or ignition coil. It is also possible to have a faulty fuel injector or an internal engine mechanical problem but these are less common. I would ask for help from a certified mechanic check over your engine to determine exactly what is causing your rough idle and stalling issue.
