Hey guys, so a couple weeks ago my 2000 Audi A6 2.7t's CEL came on. The codes came up as p0102, p1137, and p1139. These codes said MAF sensor low input, and long term fuel trim additive too rich banks 1 & 2. I replaced the MAF with brand new one from the dealer. That got rid of the MAF low input code but now I have two different codes. p1128 and p1130 which say long term fuel trim multi. too lean. I have no idea what to check now and I've gotta get the car reinspected ASAP because my plates expire this month. PLEASE HELP!
