I work at a Ford dealership in Pa and we took a 2000 S4 in on trade and I am thinking about gettin into it. It has a check engine light on so I pulled the codes and came up with a 17535/P1127 (Long Term Fuel Trim; Bank 1 Rich), 17537/P1129 (Long Term Fuel Trim; Bank 2 Rich), and a 16684/P0300 (Random/Multiple Cylinder Misfire Detected). The car has 85K on it and is in near mint condition. I'm just wondering if anyone has had this issue with theirs so I can have an idea of how much it will cost me to get it right. I'm thinking a good tune up and some new plugs might help because they seem to me like they should be related problems. If anyone could help me out it would be greatly appericated!!!!!!!!!! Thanks, Kris.

 

EVAP canister purge valve, excessive fuel in engine oil

I guess some one had a hard time starting the engine and it flooded check the purge valve out and the pipes

 

Mine had the same codes right before my MAF went, but it also had lean codes for both banks as well. Even if it is a MAF they are only like 120 brand new at the dealer.

 

Misfires and a rich code can mean bad maf,VAC leak

If it is a 2000 then I would replace the MAF they tend to go bad
