Could very well be the o2 sensor... the headers could be messing it up... do you still have the cats on there? If you took off the cats thats gonna be your problem... also if you have a lot of miles on the car you may wanna upgrade ur plugs (real cheap) to make better spark to burn more of the gas... thats all I can think of for now, lemme know how it turns out...
