Hey, I recently put a injen cai on my 6 and i keep throwing my bank one bank two exhaust code for too lean or rich in air and gas mixture.....checked the gas cap and cant figure out why it would be doing this.... i know that they say even if you blow on a mazda you throw a CEL but these are my first ones. on the intake i did not hook the sensor on the stock intake box that controls the idle point which it never said to hook up on injens website. when i did hook this up to see if this was the problem and i threw the same CELs faster actually within 50 miles and when it was not hooked up it took 200 miles to come on without the sensor on..........any i deas or remarks would be grea.......will this mess anything up if intake is left on?............and ye checked the gas cap lol(gotta hate that code)
