Signs Your Engine’s Fuel System Needs Service or Repairs

Your vehicles fuel injectors deliver fuel to the engine at precise times and precise quantities, optimizing the engines performance and fuel economy. The fuel injectors disperse fuel through a series of nozzles, and just one dirty nozzle can compromise performance. However, modern engines have sophisticated computer equipment that allows them to compensate for small errors.

The efficiency of the engines computer systems means that, in many cases, a clogged fuel injection system goes unnoticed at least in the early stages. As the problem becomes more severe, you may notice these problems:

Decreasing fuel economy

Because your fuel injection system is designed to deliver fuel in precise amounts to optimize engine performance when it becomes clogged, fuel efficiency begins to drop. If you notice that your vehicle is getting fewer miles to the gallon (litres per 100 km) than before, a clogged fuel injection system may be the culprit.

Loss of performance

If your vehicle’s get-up-and-go seems to have got-up-and-went, clogged fuel injectors are a likely explanation of the problem. Sufficient fuel is needed for proper combustion. If the engine isn’t getting the right amount of fuel, combustion may be diminished, resulting in a loss of power.

Engine stuttering and stalling

If your engine isn’t getting the mixture of air and fuel it’s designed for, it can impact engine performance, causing the engine to stutter or hesitate.

Rough idling

If the engine stalls or sputters while it’s idling, this is a sign that combustion isn’t happening as specified.

Engine misfires

When incomplete combustion occurs, engine cylinders can miss a stroke, resulting in a loud noise. When engines misfire, drivers will likely hear the noise and feel a jerk from the engine.

Preventative maintenance can help keep your vehicle running trouble-free for longer, but, eventually, you will likely need to have your fuel injection system serviced by professionals. The skilled mechanics at Import Auto can diagnose clogged injector systems, or other fuel system problems, and clean them or replace them with new ones, restoring your vehicle’s performance and fuel economy.
