Why Does my Navistar MaxxForce 13 Diesel Engine Keep Misfiring?

Why Does my Navistar MaxxForce 13 Diesel Engine Keep Misfiring?

Engine misfires are pretty common at diesel engines. Recognizing the cause of a misfire can be difficult. Sometimes misfires can be challenging to diagnose, even for skilled technicians. It would be best if you started diagnosing the misfire on your car as soon as possible, as postponing it can only increase your repair costs as time goes by.

Why Do Diesel Engines Misfire?

There are a few causes that appear more often than others. Even though a misfire may have its origins in one or more systems, the primary suspects are damaged or clogged injectors.

The first place to start looking for the misfire is by inspecting the fuel system. The fuel/air mixture needs to be balanced for the engine to start and work properly. This balance can be damaged if the fuel injectors get clogged, preventing the fuel from getting to the combustion chamber. The incapacity to ignite the air/fuel mixture in the combustion chambers will result in the engine not turning over.

After a while, your engine’s fuel injectors may weaken or get clogged up, especially if you mainly drive short distances. Stopping and starting the engine frequently can accelerate the process. Damaged or dirty fuel injectors can restrict fuel flow into the cylinder leading to an improper air/fuel ratio.

Other causes of failure for your rail injector include low fuel filtration, fuel contamination, improper install, and usage of non-OEM quality remanufactured parts.

6 Signs Your Diesel Fuel Injectors Are Faulty

  1. Rough idling – the engine seems like it will stall when you stop.
  2. Struggling to start – If the engine gets too much or too little fuel, you may experience issues when trying to ignite.
  3. Fuel odor – The smell of fuel inside the cabin while running might suggest a leak somewhere. This means that your injector is damaged, and it enables the diesel to flow out of the nozzle.
  4. Excessive exhaust smoke – Injector deposits and clogged fuel filters can result in incomplete and uneven fuel combustion, ending with a thick smoke emission from your exhaust.
  5. Fuel consumption went up – Faulty injectors will burn more fuel, which will lead to increased fuel combustion and will have a direct impact on your vehicle’s efficiency and performance.
  6. Check engine light on – The check engine light could be triggered to turn on if the engine gets too much or not enough fuel.

If you’re experiencing or suspect any of the above problems, you need to give us a call!

When fuel injectors fail, you are left with a diesel engine that performs below par. This is a financial burden to you and costing you time having to pick parts up. Who wouldn’t instead save that time and money?
