Sportsman 700 efi sputtering and stalling
2005 Sportsman 700 efi
Started sputtering and occasionally will stall.
I'll be driving around and it will get boggy, if I stop and come to an idle it will either low idle around 800 rpm or it will simply stall out. If it stalls out, I will start it and it will run fine immediately after. If it doesn't stall out the low idle will eventually clear itself within a few seconds. I can drive around fine for a bit then it will do it again. I have a flat 2 acre yard so I'm not working it hard. No warning lights showing on the display.
Things I've checked or done:
I have a fuel psi gage attached and when it sputters or stalls the psi remains around 38 psi
I checked the tps and it is at .710 dcv at idle
Pulled the plugs and they are golden brown
Fresh gas
Need help on what to do next??

Look over this "sticky" post on 700/800 efi problems.https://atvconnection.com/forums/pol...ap-wiring.html It explains about the thin wiring and also the manual states that efi problems are 80% wiring related,not a problem with sensors themselves. It may or may not throw codes when this happens,but does sound like what happens with the t bap wiring harness or connector. Erratic idle,stalling,back firing is just some of the symptoms. You can look for any visible bare wires from the t bap sensor and also feel for any soft internally melted wires and the connector itself for any pins that may have pulled back a little. Polaris "repair kits" listed for these are junk! This you can trust me on because I replaced many over and over again. If it's a wiring problems,then this place has a lot better harness repair kits than Polaris has. First repair kit listed.Only The Best

Most of the time I never had codes show up when it was a t bap wiring problem. Hope the otb repair kit solves the problem. Keep us updated.

I've got about 30 minutes on the new tbap wring so far and no issues. I'm cautiously optimistic that this fixed the problem. When I took the old one off someone else had either replaced with the Polaris kit or repaired the wiring of the original. I didn't see anything obvious when I cut the old one out.

Either one is a good enough reason why it failed. Either someones' rigging on the wiring or a crappy Polaris harness kit. Hopefully the better harness and connector solves the problem permanently for you.

I took my 700 out today, first time since my last post and it started doing it again. Its colder out 22deg out. Can tps affect this? I remember last year when I first moved the tps it was at .700vdc instead of .710. Currently I put it at .710, could this be affecting this?
