It doesn’t matter whether you are 1 hour away from home or 15 minutes from home, having issues with your car accelerating can be very bad. Not only does it cause more stress for you but if you pull out in front of someone only to find out that your car won’t accelerate it can be dangerous.

You may feel like you’re powerless and stranded. There are several reasons that can cause your car to lose its acceleration, and diagnosing the problem can be challenging. Here are some common reasons why your car won’t accelerate and what you can do to fix the issue.
One of the number one reasons your car won’t accelerate can be a clogged air filter. Your car’s air filter keeps dirt and debris from entering the engine. A clogged air filter can reduce the amount of air entering the engine, causing it to run rich, which can result in poor acceleration. A dirty air filter can also cause your car to stall or misfire. You should replace your air filter every 12,000 to 15,000 miles, or more frequently if you drive in dusty or dirty conditions. The money spent on the filter will easily be returned in fuel savings.
The second most common culprit can be a fuel delivery issue. If your car’s fuel pump, fuel filter, or fuel injectors are malfunctioning, your engine may not be receiving enough fuel to accelerate. The fuel pump is responsible for pumping fuel from the gas tank to the engine, and a faulty fuel pump can cause poor acceleration or stalling. A clogged fuel filter can also prevent fuel from reaching the engine, leading to poor acceleration. A skilled technician can diagnose and repair fuel delivery issues.

If you hear hissing, popping, or rattling noises coming from your exhaust system this could be the issue.
