So this morning I start my car let it warm up like usual 2 mins , and all of a sudden I get a engine light pop up so diagnose it and the code appears to be p0171 bank 2 too lean , its a 2012 accord exl v6 coupe .Any help would be very appreciated !!!
Instead of trying to deal with this yourself by resetting the code please do as others have suggested and take your car in to the dealer. They can diagnose and fix this far more efficiently and effectively than you can.
Ooops, page dn cut that post off. In that case, reinstall the stock intake and reset the code. The dealership is going to want you (him) to do that anyways, because otherwise they'll go straight to blaming the aftermarket part.
