Bad idling RTX

[DaMick85]

Just pulled my 2007 RTX out of storage and I'm a little concerned about the idle. It started doing this, this past winter just never had the time to look into it and the dealer wasn't much help at all. In the manual it says that when you start the sled the yellow light for the oil temp should come on and it does and says that the RPM should be between 2800 and 3000. When I start the sled it trys to kick up the RPM and gets up to about 2200 and then drops down to the normal idle of 1500. When its cold out it takes me 4-5 starts and I have to manually hold the throttle to keep it from dying. Any help would be greatly appreciated cause the dealer told me that it was a bad tank of gas. My argument is how can a bad tank of gas affect something that is electrially controlled. Thanks for any help!

I assume this is a fuelie. Right? It takes a few weeks to get back up to speed on all the features of the different sleds again. I have had at least one fuelie in "the fleet" since 1994 and have done extensive fuelie troubleshooting, in the past.

Bad gas will not burn smoothly. Also, if the gas is bad enough, the injectors can get plugged and/or stuck open. At best, the fuel distribution may not be smooth.

You have to ensure that your fuel is clean. Carbs can be cleaned. But a sticking injector is most frequently headed for the trash can. Never use a metal gas can. Make sure any containers you use are clean.

Bad fuel problems pop up soon after using a gas can or refueling from a station that has little traffic. Never use old gas. Was your sled exposed to any of these hazards, just prior to it starting to act up?

You may want to consider draining the fuel & flushing the fuel lines. Add new fuel and see if things straighten out. If they do not, you may want to remove the injectors and try to reverse flushing them with brake cleaner. Or, ... you can add some injector cleaner and run it, once it snows. Sometimes they will clean themselves back up.

If you are convinced the gas is good, have you checked the electrical connections in the injector's circuits? Also, a shorting or broken injector wire can cause an injector to not function consistently. Occasionally, injectors can fail. But usually that is because of crap going though them.
