Ok, I have a '98 A4 2.8 QT. It's been sitting since early January while I was away at basic and AIT and now it won't start. It's got fresh gas, fresh oil and filter, and the battery has been recharged. It's getting spark. It'll crank but it won't run. It's throwing 5 codes:

P1127 Long Term Fuel Trim mult.,Bank1 System too Rich
