Automobile: Check Engine Light and Car Not Accelerating

Common Reasons

When a car is not accelerating, there are several common reasons that could be causing the issue. Worn spark plugs, faulty oxygen sensors, or a loose gas cap can all cause cars to not accelerate properly. It is important to check for these issues before attempting to diagnose more complex problems.

Troubleshooting Car Not Accelerating

If the above common causes have been ruled out, then it’s time to look at fuel system issues, ignition system problems and transmission issues that may be causing the car not to accelerate.

Fuel System Issues

A clogged fuel filter, low fuel pressure or dirty fuel injectors can all cause a car not to accelerate properly. If the fuel filter is clogged or the fuel pressure is low, it will reduce the amount of fuel being delivered to the engine and can lead to poor acceleration. Dirty fuel injectors can cause misfires which will also lead to poor acceleration.

Ignition System Problems

Weak ignition coils, faulty distributor caps and defective ignition switches can also cause cars not to accelerate properly. If one of these parts is malfunctioning it can lead to misfires which will reduce power output and result in poor acceleration.

Transmission Issues

Low transmission fluid levels and worn clutches or flywheels can also prevent cars from accelerating correctly. If the transmission fluid is low this can lead to slippage in the transmission which will result in reduced power output and poor acceleration. Worn clutches or flywheels can also cause slippage which will lead to reduced power output and poor acceleration.

Common Issues That Cause Check Engine Lights And Car Not Accelerating

Poorly maintained vehicle components such as bad oxygen sensors or bad mass air flow sensors can also cause check engine lights and prevent cars from accelerating properly. Bad oxygen sensors can result in incorrect air/fuel ratios which will reduce power output and lead to a lack of acceleration. Bad mass air flow sensors can also disrupt air/fuel ratios resulting in reduced power output and a lack of acceleration.
