Thread: check engine light

    The check engine light went on for the third time, a friend that works on a gm dealer told me that it is because of the cam swap and it's weird idle, and that I'll have to live with it because no matter how many times he erase the code it will come back on.
    It doesn't make sense to me since Allen fixed idle with his tune.

    So, is there a way to fix this with LS1edit?
    Other options?

    Thanks.

    Does the SES light come on steady or does it flash? Have you had the code read yet? Sounds like a miss fire code to me. Allen should be able to fix it with edit, he did my edit and I had a few codes that he fixed. You shouldn't delete the codes you need to have Allen make the adjustments for them in edit.

    Thanks for the replies guys, the light comes on steady, the truck works fine, but I'll check the plugs and plug wires any way.

    Thanks.
