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.

You may feel  you have  poor  choices  but by not voting   you are  in effect casting a vote for the one who is the worst choice.

Never said I wasn't going to vote, even voted in the primary, just said I wish their there was someone with some brains to choose from rather than a couple of idiots

Gator idling (or trying to)

Please give me a truck driver or anyone that is not a complete idiot to vote for !!!!

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)

With fuel injection, it’s like a car… I would take the throttle body off and inspect. Maybe get some throttle body cleaner and spray it first and see what that does. 
 

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.

Do you have a smoke machine? If not, I would get a cheap one and search for vacuum leaks around the intake.

I have one from amazon I use on my cars and stuff like this, works pretty good with baby oil.

Nothing beats a cigarette, Wish I still smoked

It's likely that the O2 sensor wasn't defective. It quite likely was just struggling to control the mixture within acceptable limits and so reported it as not working. That's quite common with O2 sensors. They are one of the most miss-diagnosed components.

I'd be checking the throttle cable adjustment, the fuel flow and pressure, the IAC operation(might operate on 5volts so be careful), and the spark plug gap and condition.

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.
