o2 problem after header install
Hey guys
I did a long tube header install on my 2005 mustang GT and when i went to drive my car it threw a few different codes that all have to do with the o2 sensors, i put the extensions on and everything and am getting **** for mpg's. Im pretty sure everything is hooked up right. i dont know if i put tall the sensors in the same positions that they were in, would that even matter?

Maybe there isn't enough catalyst in the exhaust and it's tripping your sensors making them think your cats are bad, or some how in the installation the sensors where damaged. Also the positioning of the sensors... Well they have to be after the cats. Although I'm sure you did that.
