hello I have a trail master 300xrx with efi that completely refuses to idle. I am able to start it up and drive around but as soon as i come to a stop it dies. So far all ive done is change the spark plug and oil. I couldnt find any information online on how to adjust the idle and was wondering if anyone knew how/if you can adjust it.

Sounds like a dirty IAC.
They can be carefully cleaned.

So it is with cars too. Hope it doesn’t have an ECM. A faulty IAC took out an ECM on a Nissan I have. What a conundrum that was.
Ok thanks I’ll try that out tommorow and report back. Is that somewhere in the throttle body I’m really not too knowledgeable on fuel injection.
Yes defintly would much rather just clean out a carb than figure this out lol

Im not sure where it is located or exactly what it looks like.
Im assuming a typical IAC pintle valve.
Most likely located by the butterfly on the throttle body. It will have some electrical wires to it.
The engine might have a mass air flow sensor too that could be dirty.
You said it runs fine just no idle, so I would guess more to the IAC being culprit.
Post some pics and we might be able to point you a little in the right direction if your unsure.

What about the base idle, is there a screw?
