#1 – “Check Engine” Light Comes On

The clearest sign of a potential issue is when you see the ‘check engine’ warning light. Although this could indicate a number of issues, one is a fuel injector fault. An OBD2 scanner will help you to determine the exact nature of the issue.

#2 – Rough Idling or Stalling Engine

If there is an uneven or insufficient fuel supply, the RPM can drop below the optimum level and can cause a rough/violent idle. If the RPM drops really low, the car can stall.

#3 – Engine Vibrations

If the fuel injector is damaged/faulty, it will prevent the cylinder from firing correctly. This causes the engine to vibrate/hiccup.

#4 – Engine Misfiring

If the injector is clogged/damaged, then the engine won’t get enough fuel – this can cause the engine to misfire whilst you are driving. It may also be a struggle to accelerate.

Not all problems with fuel injectors are fatal, and many can be repaired/reconditioned. If you are looking for advice on injector reconditioning Northern Ireland has a number of expert companies.

#5 – Fuel Leak

A broken or cracked fuel injector can cause a fuel leak. If you have a leak, you will be able to see fuel on the fuel rail or the exterior. Fuel injector seals can deteriorate over time and may be where the leak is coming from.

#6 – Fuel Odour

An injector that is stuck open or damaged in some way is likely to cause a smell. This can also be caused by a faulty sensor or a problem with the fuel lines.

#7 – Engine Surge

If a fuel injector sprays too much fuel into the cylinder, this can lead to an engine surge. Your acceleration will tend to be much slower. You will also notice a significant RPM change.

#8 – Poor Fuel Economy

This can occur if the car’s ECU is instructing it to release more fuel than is actually needed. Over time, you may notice you are having to fill up more regularly.
