My 05 RX-1 with about 1440 kms on it has started to idle rough.

It sounds very much like it's on 3 cylinders at idle; sort of a put, put, put, put idle (consistant). Any load at all (touch the throttle, or even push down on the belt to put a little load on the engine) and it smooths out to the standard RX-1 purr.

I talked to my dealer and they said they had the same problem with another 05 RX-1. Apparently it was a bad plug.

I have a new set of plugs and will try it, but does this make sense? Running anywhere other than idle - including wide open, it pulls hard and smooth. With every other vehicle/sled/boat, etc. I've had if a motor doesn't idle well due to a bad plug it doesn't run well at WOT.

Have any of you had this problem?
 
I think you are right. It sounds like the carbs have some gunk in the pilot jets. Once you are on the hammer everything runs fine ;)!
