One of the most annoying and inconvenient issues you can experience when driving is a jerky or delayed acceleration. Moving forward is really the only thing you need from a car. So if you step on the gas pedal and your car jerks or you don’t feel an immediate, smooth response, these parts could be to blame:
Fuel Injectors
Any part that deals with the amount of fuel reaching the engine will cause the car to jerk if it malfunctions. Since fuel injectors deliver the goods directly into the engine, if they get clogged with carbon deposits and lose efficiency, you will certainly feel it. You might also notice engine misfires or stuttering when these parts start to fail. Fortunately, having them cleaned regularly will help you avoid this issue.
Fuel Filter/Pump
A clogged fuel pump will also decrease the amount of fuel reaching the engine, causing a slow or jerky acceleration. If cleaning or replacing the pump doesn’t fix the problem, check the fuel filter, since airflow in the engine is another essential aspect of clean acceleration. On the upside, replacing filters is one of the easiest and least expensive maintenance tasks.
Spark Plugs
These little parts provide the spark that ignites fuel cylinders. If they get worn out or dirty, nothing in the engine will run smoothly. Again, this issue is easily remedied, like cleaning or replacing spark plugs will have your car performing at optimal levels again.
Catalytic Converter
This part serves a vital function, reducing the pollutants that come out of the exhaust system. If the air/fuel mixture inside the engine becomes too rich, it can disrupt the exhaust, causing car jerks or the accelerator to respond when you press the gas pedal. Other symptoms of a faulty catalytic converter include foul odors and decreased fuel economy.
Air Filter
Filters keep harmful particles from damaging the engine, so making sure they stay clean should always be a top priority. To stay ahead of a clogged air filter, have it evaluated at every oil change. Neglecting this essential element can mean contaminates get into and damage the engine, which will impact its ability to perform.
Airflow Sensor
Modern cars run on a complex computer system that uses sensors to measure and control the various moving parts. If the mass airflow sensor malfunctions, it won’t send the right information to the car’s computer, and other engine components can fail as a result. Luckily, if this part is struggling, it will cause the check engine light to illuminate.
