Took the RT out of storage yesterday. Installed the battery, it started quickly. Bit of a rough idle at first but it smoothed out quickly and seemed fine.

After it warmed up a bit the idle became very rough, then the check engine light came on and soon Limp Home mode and it would not idle at all without help.

Shut it off, waited 15 minutes bit but the same result.

Took it out for a ride hoping it would clear but after a couple of minutes Limp Mode again.

Disconnected the battery for an hour then tried it again but same result...rough idle, check engine then Limp Mode.

Read the codes: P2279 and P0106 which both hint at air leaks and manifold pressure issues.

The RT ran flawlessly last season (8000Km, 5000mi). Rode right into December and it was running fine the day it went into storage. Changed the oil and ran it for a couple of hours then. Removed the battery and kept it charged over the winter.

Thoughts or suggestions.
Thanks
