RE: service engine soon light
You can check for the codes yourself by using the key on/off method. Turn the key on, off, on, off, then on and watch the CEL flash. It will flash once, pause, twice, pause, then count the number of flashes following each pause. That will give you a number. For instance, just did mine, flashed 1,2, 3,1, 5,5. The 12 is always the beginning, the 55 means it's done. Whatever's in the middle is your trouble code. If you do this and post the code, one of us will tell you what it means and help you troubleshoot ideas to fix it. You could also take it to most any auto parts store and they can put a scanner on it and tell you what the code is.
