Signs You Need Your Car’s Fuel Injectors Cleaned

You can buy fuel injector cleaner from the service station or auto parts store, but this doesn’t clean them as well as professional cleaning does. It’s a good idea to schedule a fuel injector cleaning every 30,000 miles, and your vehicle will also tell you if it’s having fuel injector problems. Trojan Auto Care is going to list the signs of clogged fuel injectors below. We’ll also talk about how the injectors work.

Fuel Injection 101

Class is in session! Basically, the fuel pump draws the gas out of the tank and pumps it through to the fuel injectors. The fuel injectors have nozzles that spray the gasoline into your vehicle’s intake manifold. The air mixes with the gasoline in the intake manifold to create a combustible mixture that is then compressed and ignited in the combustion chamber. This combustion starts your vehicle.

How Fuel Injectors Get Clogged

Burning gasoline causes carbon to build up on engine parts, including the fuel injector nozzles. This can clog them and reduce the amount of gasoline they spray into the intake manifold. The buildup is natural; there’s no way you can avoid it. As your vehicle ages, engine parts get dirty, including the injectors. When this happens in your car, truck, or utility vehicle, you will notice engine performance issues.

Symptoms of Clogged Fuel Injectors

If you have the fuel injectors cleaned every 30,000 miles, or whatever your owner’s manual recommends, you should never have a problem with clogged fuel injectors. This being said, it’s important to know the signs of clogged fuel injectors so you can get them cleaned right away. If your vehicle’s fuel injectors are clogged, you’ll have problems with

  • Your engine misfiring, sputtering, or vibrating as it struggles to keep running
  • Rough idling and sputtering when you’re stopped or sitting in traffic
  • Your vehicle’s fuel economy, which will be reduced noticeably
  • The RPM needle on your dashboard, which will dance around
  • Starting your car, truck, or utility vehicle or a dead engine

All of these things indicate a fuel problem. If you haven’t had your injectors cleaned in over 30,000 miles, that could be the problem. It could also be an issue with the fuel pump, fuel filter, fuel lines, or an unrelated engine issue such as bad spark plugs. It’s a good idea to have any engine performance issues investigated as soon as possible, so the underlying cause doesn’t create additional problems.
