I've been logging with a netbook and mmcd and running MAFT for a tuning device. My low fuel trim pegs lean and my mid and high peg rich no matter how I set the MAFT. I also keep getting random high knock count under cruise at part throttle. I have a leak on my o2 housing to downpipe not sure if that is part of the problem. Just put in a new o2 sensor which is functioning properly. Any ideas/tips?
