well about 2 months ago now i got a cel and i could never tell why i had it...but i got it about 3 weeks after i got a new resonator and muffler for my car...i did a scan with hp tuners @ my friends and i get a code P0170 lean code...i got the shop to check the exhaust and they said it's fine there's nuthin that should be leaking, so now im wondering what else could it be or is the car very sensitive when it comes to modding?
i have an 05 ss/sc with aem intake as well...
