05 GT help!!
My dad's car is having some issues. What the car has done to it is a complete Kooks exhaust (long tube headers back), BBK throttle body, BBK CAI and a custom tune. For some reason the car throws random codes at any speed in any gear at any time. Theses are the codes that he keeps having pop up: P0171, P0174 (system to lean bank 1/2) P0420 P0430 (Catt system efficiency below threshold bank 1/2) P1000 (OBD system readiness test not complete) He went back to the guy that tuned the car and they had to send out the Diablo Sport tuner, to Johnny Lightening Racing to get re calibrated. Does anyone have any ideas of what could be going on here? The guy that tuned the car keeps putting it back on the dyno and all the numbers come up good. All if any info would be great. Thanks!!
