I own a 2005 dodge neon that has been very well maintained,it has 80 thousand miles.
At 79 thousand miles the check engine light keeps coming on. Had new plugs wires, cost me 535 dollars. Light went off for a week, very puzzled.
Typically you can visit your local auto parts store and they can put a generic code reader to your ECU (main computer) of the can where you can get a general idea of what is still setting the check engine light.
Sounds like you have been doing a good job keeping up with your maintenance. I do not think 80,000 miles is unrealistic to have ignition wires replaced (if they have not yet been replaced). Perhaps you have another issue that needs attention.
That "engine light" is a computer generated signal, telling you there is some sort of emissions or electronic engine trouble. You need to know the trouble codes. When the light comes on, The code is stored in the computers memory. That code will tell you exactly what the trouble is, or guide you to the solution. You need someone with a scanner (code reader) to pull the codes and that will help you.

In nearly all cases, a check engine light does not indicate a major problem.Their main purpose is to indicate an emission system malfunction. If there is an AutoZone store in your area, they will scan it for free and tell you what the problem is. Hope this helps- thanks Super Girls Auto.

A check engine light can indicate many things.
Take to a competent repair shop and have them retrieve the codes the car is throwing due to the engine light. This means hooking up to a Computer diagnostic machine. Don't Panic~ it could be a minor item...

A check engine light can be illuminated for a number of reasons. It is an indication that the engine is not running as efficiently as possible and it needs to be checked out by a qualified technician. The tech will scan the computer for codes to narrow down the search for the cause. It can be something very simple - like the gas cap is leaking or loose, or it could be more complicated. As long as the vehicle is not running rough and the check engine light is not flashing, your car should be ok to drive until you can have it looked at.
