Check engine light on?

[customgtrs]

Check engine light comes on. I plug my SCT up and it says that it is rich. I clear it out and it is o.k. for a day or so and then the light comes on again. Suggestions. I thought about flashing it back to stock and then flashing it back to the ILLS tune.

flash it back to stock and drive it for a few days - if you do not get the CEL returning - then the tune is a tad rich, if you do - then you have a problem to fix.
