When a car sputters, there is usually a problem with the exhaust system. When an engine sputters, there are a number of possible causes. If a loud bang accompanies the sputtering, especially when the car accelerates, this indicates a problem with the exhaust system. One needs to inspect the exhaust and muffler for holes or blockages to determine which part needs to be repaired.Continue Reading
One common cause of an engine sputtering is a malfunctioning battery. If the sputtering occurs when the motor is idling, this is the most likely cause of the sound. Another common cause of engine sputtering is bad spark plugs. Spark plugs also cause an engine to sputter when oil has come into contact with the spark plug well. One diagnoses this by testing the spark plugs and visually inspecting the well.
If the car is fuel injected, a blocked or malfunctioning fuel injector might be causing the problem. When this is the cause, the inspector hears a clicking sound addition to sputtering. It is also possible that a break in the fuel delivery lines is causing a loss of power to the engine, which causes engine sputtering.
Ultimately, the best way to figure out why a car or engine is sputtering is to isolate where the noise is coming from and find out when the noise occurs.Learn more about Car Parts & Maintenance
Thin, white smoke coming from an exhaust pipe usually indicates normal condensation buildup in the exhaust, but thick, white smoke can indicate a problem like the engine burning coolant, a cracked engine block, a blown head gasket or damaged cylinder head. Thick, black smoke is generally a sign that the engine is burning excess fuel, and is typically not an indicator of as serious a problem as thick, white smoke.Full Answer >
There are multiple ways to make a car faster, such as the installation of a new exhaust system, according to CarsDirect. New exhaust systems also make cars louder, but such alterations are not always legal, explains the Criminal Justice Degrees Guide.Full Answer >
A car can hesitate or stall while going uphill for a number of reasons, but typically the problem occurs when the engine's valves and rings are worn. Because driving uphill puts the engine under additional stress, less compression is dispensed, which weakens the engine over time. Stalling can also occur when the engine's sensor no longer works.Full Answer >
A smell of sulfur coming from a car's exhaust pipe is a good sign that there is a problem with the catalytic converter, according to Cars Direct. The smell, similar to rotten eggs, indicates that the sulfur present in gasoline is not being converted to odorless sulfur dioxide.Full Answer >
