Throttle stuck wide open? Help please

[Sbeach700]

I have an 08 dragon 800 twisted turbo, my throttle cable frayed and was stuck wide open. After replacing the cable it is still stuck wide open, I know the cable is working properly now so what else could be causing this? Possibly vaccum lines being backwards or maybe an issue with the throttle position sensor? Any help will be greatly appreciated, thanks in advance.

Disconnect throttle cable at the thumb end. If is still does it then you know the look down at the throttle bodies where the cable goes make sure its not hanging up somewhere.

The cable is not being hung up on anything, could it possibly be the throttle position sensor?

Take a look at the tunnel... I had mine stick wide open because a random rock/stick dented the tunnel just enough to jam the cam on the throttle bodies.

Good be the TPS Sensor. The end that attaches to the throttle bodies is that adjusted properly?

No, not the TPS sensor.

If the cable is not the problem it must have something to due with the throttle bodies, bent/sticking linkage would be where I'd start to look.

Check the oil rod as well.

It doesn't have the oil rod.
It has the dual cable design.
I don't think a stuck pump arm will hold the throttle open in this case. I've had my pump stick before throttle was fine

Thanks guys, I'm looking into the TPS and the throttle body for damage now. I was also thinking possibly a bad gasket/ air leak at the throttle body?

Update: the TPS came unplugged, after plugging it back in it wont start unless I'm giving it a little bit of gas then once it is started the throttle is really touchy. (let off the throttle it dies, give it a little gas and it revs up high) do I need to adjust something?

 

[RDS88]

Hard to say. You would need to know if your TPS numbers are correct. Then I would suggest making sure the end of the cable that attaches to the throttle bodies is in correctly and the jam nut is tight. Also make sure the line that runs down to the oil pump is functioning properly.

High idling could also mean an air leak at the throttle body boot somewhere

Got it all figured out, ended up being an air leak at the throttle body and I gave the throttle cable a small adjustment. Thanks everybody
