Hey guys, I have a '00 Audi A6 Quattro 2.7T and I'm getting the codes p0102, p1137, and p1139 which say MAF low input and fuel trim too rich. The car seems to be running fine though. I tried cleaning the MAF when I replaced my air filter but codes came back. I unplugged the MAF and drove the car a bit and it ran the same with the MAF unplugged. If the MAF was bad wouldn't the car be running like crap? I don't wanna replace the MAF if that's not gonna clear my codes. Any advice on where to go from here would be great, thanks!
