Just bought a 2007 nissan titan in January of 2007 with 22 miles on it. I have headers, cold air intake, and a banks exaust on it. It also has a 6" lift and 33" tires. I was getting 18 miles to the gallon on the interstate with it and now im only getting 12, can anyone tell me what the problem might be? Other then the fact that an O2 sensor is not working because of the headers, and does anyone know if and when the repair kit for that will be comeing out?
thanks

You're MISSING an O2 sensor before the cat? Oi. No wonder.
