How to Know When an Engine Is About to Die

Your engine has several systems that must operate in tandem. Obviously, some components provide drivetrain propulsion, some allow you to steer and some assist in stopping your car. Because of today’s ECU-controlled cars (Electronic Control Unit), it’s possible that when even one system has a problem, your engine may shut itself down to prevent further damage to the vehicle as a whole. Ignoring such an incident could lead to your motor sustaining permanent damage and reaching the end of its life sooner than you ever expected.

Symptoms of a Bad Fuel Injector

Diagnosing engine problems yourself can be difficult, especially since many problems such as poor engine power, increased fuel consumption and higher emissions can have many causes.

Even a small amount of carbon buildup or gunk in the injector nozzle can affect this spray and cause engine misfires, pre-ignition and other drivability issues. There are a few ways to diagnose a bad fuel injector that you can try at home, though, before you go to the hassle and expense of visiting a mechanic.

At Rislone, we always advise customers to closely monitor how their engine is performing as a guide to determine if something might be wrong with their fuel system. Things such as:
