Q: Van misses and sputters

asked by on

My van misses and sputters. There may be a problem with the electrical under the dash.

Ignition coils are a common issue with this engine. Another is leaking tube seals in the valve cover allowing oil to soak the spark plugs and cause a misfire. You need to identify which cylinder is misfiring, this can be a complicated task. A trained technician, like one from YourMechanic, can help you with diagnostics and repair of your vehicle.
