The check engine light on my ep3, seems to be going on and off ever since i owned it. The light comes on for about 20-30 miles turns off for a while (few days).Then i will turn it on and light is there. Has this happened to anyone else? my car has 97xxx miles if that makes a difference.

 

Have you ever taken it in while the light was on? Go to autozone and have them scan it. It is free

 

Agreed!

If I'm not mistaken even if the light is off the code will be stored in memory (not 100% sure but that was the case for me when this happened)
