The dreaded check-engine light. When it comes on, it probably sets you into a panic. The check engine light is one of the most frustrating pieces in your car, because it does not give you any indication of what's wrong. It could be a minor fix that will cost you a trip to the auto parts store and $25; or, it could be a major fix that, when all is said and done, could cost you the car. So the next time you see that little light turn on, think of these common reasons as to why.
Loose Gas Cap
A gas cap problem is probably one of the most inexpensive reasons your check engine light comes on. When the gas cap is loose, fuel vapors can escape and really throw your fuel system off, not to mention cause an increase in gas mileage.
To determine whether or not this is a gas cap problem, when the check engine light comes on, and your car is not otherwise giving you other issues, pull over, check for cracks and retighten the cap. If the gas engine light turns off, then your problem is solved.
Spark Plug Problem
Another relatively inexpensive problem to repair is a spark plug. The spark plugs seal the car's combustion chamber, to allow combustion in your engine. When the plug fails, you may feel a quick jolt in the car's acceleration. Most spark plugs can go a very long time before they need to be replaced, but that doesn't mean problems can't arise now and then. So when you see the check engine light come on, and you've felt that jolt in acceleration, replace the spark plugs to determine if that was the issue. Another indication of a spark plug issue is the car turning over but not starting when you go to start your car.
Unfamiliar Noises
If your car has been making some funny and unfamiliar noises, and your check engine light comes on, this may be the sign of a more serious, and expensive, problem. This could mean a problem with the engine's cylinders. Or, if you hear a grinding noise when you're starting your car, it may be the starter motor needs adjustment or replacement. Grinding noises as you shift gears could be what you fear the most: transmission trouble.
Suffice it to say that any time your check engine light comes on, it's best to take your car to a certified engine repair specialist like Joe Troegner Auto Service for determining the exact cause.

When it comes to auto repairs, I am lucky. A good friend of mine is very car savvy and is able to make the majority of the repairs that my car needs. However, recently he sprung a question on me that surprised me. He asked if I wanted him to install a new part or a quality used car part. I asked for his opinion and did some research online. I was surprised to find that there wasn't a lot of information out there about when you should and should not use used parts in your car. So that's how this website came to be. I decided to compile the information I learned, so that in the future, someone doesn't have to search all over to decide whether to have a new or used car placed in their car. Hope my website helps you to make your decision!
