Rn85 - 22R Carbi Issue

[attritus]

Hi & Help,

When I'm driving, my 1995 Toyota hilux 22r carbi (RN85) won't cut back to idle when I take my foot off the accelerator. It holds the high revs until I almost come to a stop at the traffic lights for example. It won't cut back to idle even if I depress the clutch or pump the brake. Please note it does cut back to idle when you rev the engine when stopped. The problem I'm having only happens when the vehicle is moving/ driving. Any idea as to what is wrong with my carbi and what I need to do to get it fixed.

Cheers.
