So, as the performance of your engine starts to diminish; the system might exhibit warning signs that are unique. Understanding these signs will assist you in; identifying when they occur and what to do when it happens. Finally, remember that your engine is an extremely complicated system. And, as such, requires preventative maintenance.

  • Check Engine Light Activates
  • Loss Of Engine Power
  • Poor fuel economy
  • Different Or Louder Noises
  • Engine Stalling
  • Odd Smells
  • Engine Keeps Running After Ignition Is Off
  • Rough Running, Misfiring Engine

Finally, the computer monitors functions of a number of engine compartment components. And, when a problem develops codes; which relate to the particular system; will be set and retained in computer memory. As a result, when this happens, The check engine light on the dash will illuminate.

So, a hard fault will cause the light to stay on continuously. Consequently, this is the easiest problem to find because, the problem is there; right now. But, if the light comes on and goes out; the fault is intermittent. Also, meaning the problem was there momentarily; but has cleared up. Finally, both of these conditions will set computer codes; that are retained by the computer.


So, there are certain things that must be done; prior to replacing parts or performing service. Finally, you have to know what the problem is, before you can know how to fix it.
