DALLAS 2

HI THERE. MY R32 GTR HAS THIS DAM APEXI MISFIRE ALSO. WHAT I HAVE NOTICED AFTER HAVING THREE SETS OF O2 SENSORS INSTALED THAT ONE OF THEM WILL ALWAYS SHOW THAT IT READING JUST ABOUT ZERO IF NOT ZERO VOLTS WHEN THE CAR IS WARM OR HOT, FROM DEAD COLD START YOUR CAR AND HAVE A LOOK AT YOUR HAND CONTROLER AND KEEP AN EYE ON THE O2 SENSOR VOLTAGE WITH BOTH OF THEM TURNED ON AND SEE IF THE NUMBER TWO O2 SENSOR STARTS TO LOOSE VOLTAGE AS THE CAR WARMS UP. WITH MINE IT IS ALWAYS THE NUMBER TWO O2 SENSOR ON THE HAND CONTROLER. THE NUMBER TWO O2 SENSOR ITSELF IS IN THE POSITION CLOSEST TO THE FRONT OF THE CAR. I HAVE ALSO NOTICED THAT THE MISFIRE IS THERE WITH THE O2"S TURNED ON OR OFF. I HAVE HAD MY CAR TUNED BY 4 DIFFERENT TUNERS TO TRY TO GET RID OF THIS MISFIRE AND NO LUCK. CAR RUNS A NICE POWER OF 384.4 HP AT THE WHEELS.SOME SAY THAT THE APEXI IS THE WAY TO GO BUT FOR MOST OF US WITH R32 GTR,S. ALL THE BEST
