Q:

What causes a car to stall when accelerating?

A:

Some of the reasons that a car can stall when accelerating are a defective throttle position sensor, low fuel pressure and spark plugs that need to be replaced. When the "Check engine" light is on, a code scanner can be used to identify the cause more accurately.

Replacing the spark plugs, distributor caps, fuel filter and air filter should correct most issues that cause a car to stall during acceleration. If the problem does not stop, take the car to a mechanic to look at the fuel management system, throttle position sensor and the mass air flow sensor or to verify the reason for the "Check engine" light.

  • Q:

    What causes a car to throw a rod?

    A:

    A thrown rod is usually the result of metal fatigue, insufficient lubrication or over-revving of an engine. When gasoline combusts in a cylinder, it drives the piston head downward, pushing the connecting rod and turning the crankshaft. If the metal is weakened, the connecting rod between the head and crankshaft may break. Poor lubrication can cause friction, and over-revving may produce more force than the connecting rod can handle.
