I just purchased a 2012 commander 800 it has a few issues, it keeps throwing the code p2279 wich is a air intake leak. I have replaced every o-ring on the intake and resealed the airbox. The plenum isn’t cracked or leaking anywhere that I can find I have used the propane method and ether spraying the whole intake system with no change in the idling wich it won’t do unless I hold the fuel pedal halfway in. I’ve changed the mapts sensor and the throttle body, new spark plugs fresh fuel and all, and it seems as only the front cylinder is firing, the rear exhaust doesn’t get as hot as the front after idling for a few minutes but if I unplug the boot off the plug it will eat you up lol any ideas?
