Code P0171 after CAI install.

Installed a Fujita CAI and now the CEL light is on and it's coding P0171 and the one for the MAF.
So I know all the fitting are good and the hoses are not cracked. Anyone run into this and get a fix. Besides going back to stock.

clean the maf sensor and try it again, make sure that when you install the maf onto the intake you push it in all the way, cant be any gaps.

It's common for the CEL to come on using that intake. Do a search and you'll see alot of others saying the same.

No way of getting the CEL light off except for putting black tape over it ....the light will just keep coming on with that intake it means no harm at all. I have the same exact intake
