Help with engine fault code

Recently got 2 "service engine soon" codes that I was able to read on my Cobb Accesport.

First code was related to the evap emissions control (sorry guys I don't remember the actual number)

Second code had no description. My accessport stated "no description available"

The code was either P321c or P0321c (sorry I don't remember but it was one of those two). I could not find anything on the internet.

I cleared the codes and reset the ECU. After driving 4 different times today, neither code has returned.

I wouldn't worry about it if the codes didn't return. Can you see pending codes with Cobb or only hard fault codes?

evap codes usually mean leaky gas cap - had it in my rx8 once.. gas cap was shit. replaced it and the code went away after a few days of driving.

same thing in my winter beater (TC).

make sure the gas cap is tight and see if it comes back

I attached something that has helped me a lot. ive been able to identify a lot of codes from cobb, jb4, and OBD2 scanner by using the attached document.

It says N55, but I imagine that the moajority will be the same for many platforms.
