2024 GTI 130 IBR P2279 - U3FFF - C0073 errors

[kdeniz]

Hello everyone,
While at sea, the engine suddenly shuddered and stopped and never started again. I brought it home and it started but it runs shaking and fluctuating. The jet ski is only 20 hours 2024 model 130 IBR model. It has never been under water in any way. I changed the spark plugs today and the problem is not solved. I have P2279 - U3FFF - C0073 errors on the screen. what could be the problem?

The manual lists P2279 as an air intake manifold leak downstream of the throttle. I recently read a thread where the owner described his situation and he found multiple loose hoses on a new ski; we also noticed a lot of loose hose clamps on our 2023 GTR 230 as we were installing a RIVA stage 1 kit on the ski.

I'd suggest a smoke check of your intake manifold.
