I just now logged a lot of data. With the Maf. At idle just now I was at 3.2. The strange thing is.......when I hit the gas for min just to get a jolt it hit 70. On the open road I hit 150 at 6500. It consistently jumped up when I floored it and hit no less than 130+. I will have the sap fixed soon to get a clear reading. I did notice that the o2 sensors zeroed out when I floored it. I dropped off to idle and it stayed 0 until I hit the gas
