Already had the throttle body off and it wasn't really dirty. Cleaned it anyway with Brakleen followed with carb cleaner. Only time it threw a code after I cleaned it (probably residual solvent in a sensor. Have drained the gas, put in fresh gas and seafoam, but same thing, no change. I haven't pulled the injectors, but they ohm within range. Like I said, I am at a loss and Vaseline might be the only way? BTW, for all those that don't know, on expensive equipment you can put it out to bid. If I need a throttle body, I got a quote/bid for $825 which is much better than the $1,245 from John Deere.

After going through the entire service manual with the same issue and no solution. Manual stops at "service ADVISOR". So, will probably need to get a jar of Vaseline and go to the John Deere dealer.

Gator idling (or trying to)

You can adjust the throttle in the throttle body but would have to set it to about 4,000 rpm to keep the motor running. Low idle is entirely different than erratic idle (up down, up down -> dead)

Not much to the throttle body that you can access. There are only 2 little holes where are the good stuff is located that cannot be serviced. Just pulled out the entire throttle body and cleaned it (wasn't really dirty) but don't expect it to do much.

Nothing beats a cigarette, Wish I still smoked The 02 sensor was bad (threads were stripped and it fit loosely in the housing but wasn't the real problem. Can disconnect both 02 sensors and no change. Throttle cable not really adjustable and IAC is integral to the throttle body and not serviceable.

That is the problem with this machine. Everything is in the throttle body ($1,200+). Haven't found a vacuum leak.

OK, now that we are through all the BS and I simply purchased the service manual, let me tell you the problem with the machine while I dig into the manual... The engine starts fine but does not idle. You have to keep pumping the throttle to keep it alive. You can go fast down the road and she goes, but idle no. It did have a bad 02 sensor but fixing that had no effect. In fact, unplugging the 02 sensor does not make a difference. Have not unplugged both - will do that tomorrow. The problem with the 850i is that all your sensors are in the throttle body and are not serviceable (and it is not a cheapo piece). Will probably have to start ripping the engine apart?

I have yet to find a free manual. The TM109919 is for all years so the 2014 would be fine. So again, what are my choices (cant find a freebie): 1. Post a bunch of worthless posts just be be cheap and get the manual for free 2. Buy a manual on eBay for about $30.00 (a CD) 3. Buy a download from some other stranger for $25 4. Donate $29 to you folks. I think I will choose #4 as I need it now, Maybe you folks will have the parts manual too and make it double worth while.

From Arkansas. Just bought a 2012 Gator 850i RSX because I could not pass up the price. BUT it has an idle problem. So, to be honest, I joined just to get a service manual. I have a choice: 1)Buy a hard copy: ~$100; 2)Buy a CD ~$35.00; Get a direct download for free posting 10 times; or get a download for $29.00 (subscription). Haven't decided what to do yet.
