ok so this is the story, i just installed a injen intake on my evo 9 and have gone about 100 miles on it so far. then i came home and unplugged that stock boost controller(i have hallman maual so no need) and then the light came on, so i plugeed it back in and just let it sit there but now theres 2 codes, wastegate malfunction and bank 1 sensor 1 o2 sensor, i tried unplugging battery and pluggin back in but doesnt go out. HELP please

 

Go to your local auto parts store, borrow a scanner to shut it off.

 

they wont shut off codes, only read them, but i wanna no why it came on

 

Did you hook the BC up backwards? I have a scanner that will shut off codes.

 

Bc?
