hey, i get a CEL every time i drive my car the first time in a day and i'm decelerating.
i noticed also when i'm datalogging that the little 'LED' indicator comes on when i let off the throttle, it's very intermittent and seems almost random however it only comes on when i have my foot off the throttle.
it's not throwing any codes and all the sensors are in check, i have no idea what could be causing this other than possibly a faulty blue box?
any ideas?
