Gday guys wondering if anyone can help with this one. We have recently fitted a Harrop blower on a boss 315 built motor stock camshaft deal, car drives immaculately, makes excellent power and fuel trims are within two percent. After driving the car for an hour or so both oxygen sensors will bottom out and become unresponsive adding fuel to the point where it'll miss and carry on , then all of of a sudden it will all go back to normal like it never happened. any suggestions would be greatly appreciated as everything on the car has been replaced.
