Need Help....Stalling Polaris Ranger

[thompra]

Need some help from a mechanic...

My Polaris Ranger 700 XP will stall occasionally at Idle, and also after driving for a while, if you stop, right at the point that you try to accelerate. This is all intermittent.

Fuel is good, new air filter rear, front filters clean, battery good charge, new plugs, belt is great, cant see any visible issues anywhere.

Any ideas, I'd rather not take into the shop just yet.

Thanks for help in advance gang.

If everything else is OK, then just adjust the idle up a little faster.

There is a built in diag that will provide blink codes on the dash trouble light and possibly a path to follow. What year is it? I'm not sure if the newer ones with the speedo use that trouble light or something through the gauge cluster.

I sent you a PM and may have something for you.

Are your tires stock or an upgrade? If they are bigger or a more aggressive mud paten you my have to beef up your clutch with an aftermarket clutch kit. You say your belt is great but if you have upgraded your tires, you should look at upgrading the clutch components too. On the flip side, if you still have your stock tires but are very worn making them smaller in diameter, your stock clutch spring might be working beyond it's limits, stalling the motor.

I have an 05 Polaris 700 EFI and I have been having some problems
like yours. I took it to Polaris and after two weeks they gave it
back saying they think it may be the fuel tank. The fuel pump is
in the fuel tank. I have done alot of reading on differnt forums
and have found some who say it is the fuel pump. I see all sorts
of ideas. I think that the fuel pump may heat up as the gas gets
lower. I read where a guy would put gas in his tank when it started
running bad and it would correct the problem. The gas from the can
may be just enough cooler to cool the pump. I wanted to try that
this past weekend and carried gas with me but it ran fine all
weekend. So i am still looking.

Make sure your vent hose on the fuel tank is not cloged or kinked.

How is the idle adjusted...does that have to be done by a dealer with software to adjust the CDI.....?

And this would effect the Ranger sitting still at an Idle?

What happens to your engine after 5/10 minutes of running? It gets hot and any crap that is in side the engine that shouldn't be there in the 1st place gets into areas it shouldn't be. It is the same with your clutch. Once it heats up sometimes it wont behave the same way when it's cold because of a number of reasons including built-up crap and failing clutch components. It was your statement that "My Polaris Ranger 700 XP will stall occasionally at Idle, and also after driving for a while, if you stop, right at the point that you try to accelerate. This is all intermittent." made me think out side the box in the first place. Your cluch could be sticking. The size of the tires and the aggressive nature will most definitely change the way your clutch works with your type of transmission.
Cheers Mike.

Thanks for the feedback
Tires are stock. good condition. I can reproduce the problem by simply incrementatlly slowly pushing down the accelerator. At the point at which the idle starts to increase, if I do it slow enough, the engine dies.

sounds like the 'tps' throttle position sensor to me
could be going bad
or
it may need to be adjusted

[thompra]

How is it adjusted ?

the TPS is usually something the dealer takes car of- But if it is something you want to tackle- I would highly recommend you getting a service manual for your year and model. Each year has different settings. Follow the manual for detailed instructions.





Preparing / checking





Follow manual instruction to remove the tps, remove the cover & cable, back out screw.





Then install new tps. 1 screw and cable harness disconnect / connect.

Adjust the "TPS" to .528v (factory spec.) firm up screw.





Adjust throttle body to .660v (for 2006 700efi 6x6) with the funny turn screw on top. (** .710v for 2007 **)





double check all numbers and settings- these are important to the efi computer.
tighten tps screw.
triple check all numbers and settings- these are really important to the efi computer.
