High Quality Diesel injector Nozzle DLLA150P1163 0433171740 Fuel Nozzle Spare Part

If there is something wrong with one or more of your car’s fuel injectors, then it won’t run properly, or may not run at all.

Here’s a run down of the main faulty injector symptoms that will affect most cars. You will need to have the car ECU scanned for error codes to be absolutely sure that it’s an injector problem. Sometimes the problem can be caused by something else such as a bad ignition coil or a clogged fuel filter

1. Engine Management Light On Dash

This doesn’t really tell you anything, except that there is a problem with the engine. A faulty injector will cause the engine to misfire, and this will trigger the engine management light. You will need to investigate further to narrow down the cause of the misfire.

2. Car Won’t Start Easily (Or At All)

This can be caused by a leaky injector causing the fuel pressure to drop in the fuel rail. A smell of unburnt fuel from the engine bay can point to a leaky injector. Any possible fuel leakage should be investigated straight away.

3. Engine Knocking And Vibration

If an injector is partially blocked, then the right amount of fuel won’t be getting into the engine cylinder. This will cause knocking and excessive engine vibration. There are lots of other causes of car vibrations. Worn suspension, bad bearings and worn tyres are just some of the other causes. Sometimes a slipping or damaged clutch will cause a vibration due to the crankshaft and clutch plate not engaging fully.

4. Poor Engine Performance

A badly performing injector will affect the running of the engine. Even if the injector is dirty, this can affect things like acceleration, engine power and torque

5. Poor Fuel Economy

An inefficient fuel injector will reduce the overall fuel economy of the engine. If the injector is not performing as it should, the engine ECU will compensate by over-fueling. This causes the engine to run “rich”, leading to more fuel being used than necessary.
