Re: 06' XP 700 Ranger idles ok but back fires and chokes when up accelerateing
Checki the wires to the Tbap sensor located between the throttlebody and the air filter in the air tube, The wires there will break right at the connector, but the plastic will remain intact, so you have to lightly pull on them to see if they stretch. Sometimes those wires will rub on the frame and ground out also. I'm betting thats your issue. Polaris sells a replacement Tbap harness.
