  1. You Drive a Stick Shift Car

This is just a side effect of using a stick shift, not an issue. As you change into each gear if you’re still learning, you can experience some jerking.

However, manual transmissions frequently experience it, so as you become accustomed to the controls, your ride will be more comfortable.

  1. Worn Out Spark Plugs

The function of the spark plugs is to ignite the mixture of fuel and air kept inside the engine, causing combustion that drives the pistons in your car.

Therefore, there’s a significant probability that your spark plugs (or the cables that connect to them) are the cause of your car’s stuttering.

These auto components frequently wear out, and a malfunctioning spark plug will make your engine misfire, jerk when you speed, and be more noisier than typical.

The main function of fuel injectors is to continuously supply gas to the engine’s cylinders.

Your engine won’t receive enough gasoline and won’t operate properly if your injectors become too dirty, frequently misfiring while you accelerate.

The good news is that cleaning your fuel injector only takes a few hours, and most garages can take care of it for you.

You can also clean them yourself by putting cleaning fluid in an empty fuel tank or using other techniques that call just a few tools and some auto expertise!

  1. Dirty Air Filter

The ideal balance of the air-fuel mixture is the dream team that keeps your car running smoothly.

Unfortunately, some dirt will start to sneak into the engine and start to influence how smoothly it runs when your car’s air filter becomes overly clogged with dust particles.

Your filter is simple to check, and if it has to be replaced, the cost of the repair is extremely little.

Or you might use a reusable filter that simply has to be cleaned.

  1. Moisture on the Distributor Cap

The distributor cap on your car is a crucial component of the ignition system.

The ignition coil cannot transfer electricity when moisture accumulates, which causes the automobile to jerk.

In the chilly, snowy environment of Ottawa, this frequently occurs! Fortunately, this doesn’t require replacement. Simply let the moisture evaporate.
