What do you guys think? I was driving it a little earlier before and already got a system too lean code...
Also, the heater nor the a/c blow. I was thinking maybe
the actuator, but idk someone help me on both please !

 

Looks nice! Congrats!

 

Check for modifications to the air intake system along with air leaks.

If the blower isn't working, then it might be the blower switch, blower resistor, or blower motor.
