I was just wondering if it may cause a little bit of a miss during a light load. I have been struggling with this miss for a while now and i am out of options. It just feels like a dead miss at low rpms and under load until its on the floor. Its fine after that. Just wondering if this could be a tune issue or if the 02s being turned off could cause a rich or lean condition under part throttle. thanx for the info. Kevin

Turning off the front O2s means that you loose adaptive learning. The maf xfer needs to be calibrated really closely since the car can't learn any more. I would put a wideband on it and see what the a/f is doing when you have the miss.
