Heres a run down:

Sat: Installed AP Stg 1( Running great)
Sun-Fri: 600miles (runninng great)
Friday night: 250miles to Vegas
Late Friday goto Haufbrauhaus for beer, sitting in traffic a bit, through a P0171 code Cleared it thought it was a fluke.....
Sat ran 50 miles, no CEL
Sat night, P0171 again!

It seem to happen after a long run and a restart of the car.

Mods: Stromung catback, GTmoto delete, and a KN panel filter.

any ideas?

 

cleared for a week

 

threw another CEL last night
\
rechecked my air box.
seems like when i replaced it with the KN it desnt fit as easily as the stock filter. the 2 rear tabs were on snapped in. had to take the entire box out and put the tabs in and and put assembly together and then reinstall the entire airbox.

will monitor again.

 

yea i actually noticed this when i removed the snorkus today. the factory airbox has tabs facing the turbo that need to be secured before snapping in the metal clips at the other end.

when placing the top part of the box in, start with the side closest to the turbo. lign up the little notches and make sure they go under the lining. make sure the right side looks sealed.

then lower the left side and clip in with the metal tabs. hope this helps a little, if you haven't already done it
