It is without a doubt that when your BMW starts to stutter as you accelerate, it usually means there is a problem on the radar. The issue of a car jerking occasionally when accelerating is one that many BMW owners encounter.
Here at Oceanside Motorsports, we have BMW experts that can assess why your BMW is stuttering when accelerating and we can find out what’s wrong with our diagnostic testing to ensure you’re only spending money on what needs to be fixed.
Here are the reasons why your BMW is stuttering when accelerating:
- Bad Spark Plugs
One of the most frequent reasons for cars to stutter is worn-out spark plugs or the electrical wires connected to them. When you accelerate, your BMW jerks because the engine misfires due to a faulty spark plug.
- Bad Fuel Filter
An engine may shake or stutter depending on the level of the fuel limitation brought on by a dirty filter. Under normal driving circumstances, there could be no symptoms, but a blocked fuel filter will limit the engine of the additional fuel it needs while accelerating quickly.
- Timing Belt Issue
More major problems, such as loss of compression and engine stalling, are brought on by a worn-out timing belt. Additionally, once the belt slides, it won't automatically realign to its ideal position, causing the issue to continue frequently.
- Fuel Pump Issue
The fuel pump's difficulty to consistently inject fuel into the engine as a result of inconsistent pump pressure is what causes this stuttering or jerking. The pump is probably malfunctioning if the engine stutters when accelerating.
- Check your throttle body
The throttle body or an idle control valve regulates the smoothness and speed of your engine's idle. Poor or low idling is one of the warning signs that the throttle body is not working properly. This includes a very low idle after starting the engine, the engine stalling, and the engine stalling when the accelerator pedal is depressed quickly.
- Blocked Catalytic Converter
The amount of pollutants that escape from a car's exhaust is decreased due to a catalytic converter. When the air/fuel ratio in your engine is excessively rich, a blockage might eventually form in the catalytic converter, messing with the exhaust system's circulation. When you press the gas, this may cause stuttering, jerking, and a general delay in responsiveness.
