Q: Truck stutters when climbing long inclines

asked by on

My truck stutters when climbing long inclines at 50 to 55 MPH. I am also getting short bursts of lost power. The shop said that the spark plugs are getting fouled by coolant. The truck does have 240,000+ miles on it.

The motor is probably shot. It sounds as though the head gasket is blown, allowing coolant into the engine; when that happens, all you can do is replace the engine or rebuild it. I would recommend taking it to a mechanic to have the stuttering issue closely inspected.
