I am having an unusual problem with an '06 R1 engine. Number 3 cylinder is overfueling. The engine usually idles and runs well but occasionally at idle it will drop number 3 cylinder and raw fuel runs out of the exhaust. On the track the car bogs down on the exit of 2nd gear corners. It is intermittant but when it does occur if I check the throttle bodies, number 3 cylinder is wet.
I have changed plugs, coils and injectors but it is still happening. I don't know if it is an injector staying open or the coil not firing. It is a stock ECU and is showing no fault codes.
Anyone had this before?
Cheers
Greg
