Question CEL but no code found?

So I'm running a cobb stage 1 v1.19 (stage 2 any day now) and I got a CEL last night. Hooked up the AP and it says no code found!

Anyone ever seen the CEL come on without a code? Think it's a problem with the reflash, or with the AP itself?

you might be getting knocks... if the CEL lights up all the time, that means it's a "real" cel.... if it blinks thats a warning that your engine is knocking...

It's steady, not flashing. Does the stock (or cobb) ecu flash for knock?

The AP does not read all codes...you need a OBDII scanner for that.

i just got this same code after putting on an sti up, anyone have suggestions? (P2004 from autozone). It only comes on after a cold start where the car will run at 2k rpm for 10 seconds and then go down to normal, if I clear, it'll stay off until the next cold start.

i have the same code, all you have to do is blimp the throttle right after you start the car cold. that will prevent the p2004 from coming on.
