I know there has been a lot of posts about this issue, but i cant find one just like mine. i was driving on the freeway at 65mph with my cruise control and i got off on an exit. i turned off my cruise control and drove at 55mph for about a mile and my cruise light starts flashing and my check engine light comes and stays on. i get back to the house and try checking it with my accessport. but it cant find any CEL codes. i reset the ecu and it doesnt come back (for now). i was just wondering if anybody has ran into this. and if it helps my mods are accessport stage 2, k&n drop in, cobb down pipe (cat less) and espiler cat back.

 

Every once in awhile, a waste gate cycle code will bring up on mine, but I usually see the code on the accessport. The only time I have ever had the check engine light is on without a code is when I forget to unplug my green diagnostic plugs,
