Finally, the 900 is registered, insured and ready to go. I've been driving it and have noticed recently that the idle isn't quite the same as it is when I took the car off the road. Cold its sputters a bit, which I usually had but when its warmed up, it'll idle around 1500-1700 RPM and will, only sometimes on occasion, go down to around 1100 RPM. I'm guessing that the engine is somewhat racing so this is causing my temperatures to rise higher than normal, above 3/4 the way. Any suggestions?
