I have an 02 LQ9 with an ls6 manifold, ZO6 MAF, 80mm throttle body. The car idles fines but as soon as soon as I try to drive down the road, it starts running like crap. Give it gas and it wants to stall. My Air/fuel ration with start around 12.47 then drop to 10ish when trying to drive. All of this is with the MAF plugged in. If I unplug it, car runs fine. I'm going to check for 12v later at the pink wire on the MAF. I also have the MAP sensor installed, I forget which one. I know it's off a cobalt ss so I can run SD down the road. Thanks for the help guys
