2008 Polaris Ranger 700 XP 4x4 EFI
Im working on a friends 2008 700 EFI that wont idle. Other then oil changes he hadnt serviced it since he owned it. I did a full service on the machine before tackling the wont idle part. Replaced the air filter and spark plugs, wires, as well as the crankcase breather assembly. I checked for codes, none present. Check fuel pressure, it stays steady at 39 psi. did a compression check of both cylinders both are at 160 psi. Inspected the tbap, and tps wiring with only one wire showing wires. I also adjusted the TPS to spec of .660. I can get it started by holding the brake and giving it throttle but once it is running it is surging. I also have a new throttle boot in route. i couldnt find any cracks but cant hurt to change it right. Any help on getting it to idle and stop surgin would be apreciated.
