I have a 2006 Nissan Sentra and i put in a BlingLights Cold Air intake. it works perfectly fine. i installed it back in april, and drove it until june when i started having troubles with my low gas mileage.. mind you i drove from new york to florida, about 2,800 miles averaging a nice 39 mpg in the process.. but as soon as i get down to florida i get a check engine light on, so i think "ok i'll take it to a dealer and they replace my air/fuel ratio meter, so then 2 weeks later my check engine light comes on and i take it to auto zone and it says that my O2 sensor before my Cadillac converter needs to be replaced, so i go to the dealer again and they say because i have my air intake on that they cannot replace it because it voids the warrenty. after that they reset my light and i have been averaging 22-23 mpg where i should be averaging 32-34mpg... is this because i do need a new O2 sensor? or did they mess with my car because i have the intake on it trying to get more money from me?
