I put the reverse to 3 just now and haven't loaded to the car yet. But I don't have the rear O2s hooked up but have them tuned out. I also thought I had everything right for the MAF to not show up but guess not. Before I go to get inspected I know I need to do plenty of drive cycles but what exactly will they see when they hook up to the OBDII? You can have 1 not ready code and that's it. When I clear them while driving the MAF pops right back up.
