2012 RTS (Red, of course) engine missing, erratic auto shifting, and quitting at idle frequently.
Then running OK for a while. Then badly again.
Fault codes P2279 Intake air leak
P0172 System too rich bank 1.
P0175 System too rich bank 2.
Dan at Simi, Ca. Can-Am found:
Hoses at both sides of throttle body to manifold air pressure sensor broken/cracked.
Replaced hoses with stock, no fault codes, runs great.
Hoses should last a bit longer than this! Might be a good thing to check.
