[QUOTE="ToledoDan, post: 759195, member: 13704"] i have had issues with the o-ring in the fuel pump getting displaced. but once it is displaced it will not go out of limp mode. mine is going in and out of limp mode, so its probably not the o-ring, but could be another issue with the fuel pump. the 520344 [U]17[/U] is a rich condition code, I believe 520344 [U]15[/U] is a lean condition. other two codes are misfire codes for cyl 1 & cyl 2. I plan to do the tune & clutch upgrade, change spark plugs and clean air filter (we rode dunes for 6 days on the last trip so it got a little dusty and that could have contributed to a dirty air filter and rich condition). sounds like i'm jumping off the deep end and doing the tune and clutch kit to fix this problem, but just don't want to go on another ride and have to deal with phantom problems. if that don't get it, fuel pump will be next.
