yo,

My car is running great, getting 23-25 mpg highway, strong acceleration, solid starts etc etc.

HOWEVER! My OBD is still showing code 2-3-1 (no check engine light though)
If im not mistaken, 2-3-1 means "fuel system compensating for rich/lean mixture at cruise"

Having just recently fixed my flapper/thermostat assembly in the airbox (and by fixed, I mean i ripped it out and blocked the hot air inlet) and because of that, I have no idea how long hot air has been coming into my engine, thus slowly killing my AMM.

What do you think? AMM? Suggestions? oh by the way, the rest of the fuel system is great and recently serviced (everything from pumps, relays, FPR etc.)

Thanks in advance
