Well, I thought I had my Disco fixed, but the Check Engine light came back on and I checked the codes P1176 Max Positive Correction FMFR and P1178 Max Positive Correction AMFR. I have no idea what that means. Land Rover told me it was probably the gas cap, but if not then the MAF sensor or an oxygen sensor. I flipped the gasket on the gas cap, thinking that would help...apparently not. Any suggestions short of $600 for a MAF sensor or 4 O2 sensors at $150? Thanks. BTW..It isn't running bad and gas mileage is holding up....I'd just keep driving, but I know these things just get worse.
