Default ST codes thrown

I have on 02 WRX w/vf34 and a FMIC. I am throwing a code of 303 and ?????

I know that the 303 is the misfire on #3 .
What the heck does "????" mean when it is thrown?

About 3 weeks ago my car through a 302 303 304 and ???? after a stubble from the take off.

Got home and found out that my blow off valve was unscrewing itself , I think do to the solid pitch mount. So I fix it and reset the codes and it drove like a champ.

Today I was just casually driving and the CEL popped on again. Checked it right away and gave the prementioned CEL's.

Could this be a fueling problem? I have changed my plugs recently , could it be a misgap?

I know this is a hard problem to solve without actually driving the car , but some trouble shooting would be helpful.

I am going to check on all the IC for leaks/BOV crap, just to get that out of the way.

I did however , after the CEL was thrown , push it up to the upper RPM's to listen for DET but everything sounded fine, no pings from what I can tell.

As soon as I can I will data log to see if I can find anything.
