My new RKC broke down on the highway the other day. Service guys say that fuel is leaking into one of the cylinders. That's the only issue. I discovered that problem on the side of the highway after pulling the spark plugs.
Is the motor stock?? Sounds like one of the injectors is hanging open. Keep us posted, it would be nice to know if the MOCO got a bunch of bad injectors or if this is an isolated incident
