22RE idle adjusting

Have put a 22re in my 85 hilux.

Having trouble with ruff idling, idles low and dies. Tryed to adjust but im not sure if im doing it right.

Im adjusting on the screw (hexagon with nut) located just about in the middle of this pic :



Isnt it the right one ?
Have changed fuelfilter, so that shouldn't be the problem.

the flat head screw on the throttle body adjusts the idle as well...

The truck should idle high when cold then settle to about 725 or so when warmed up... I'm guessing that's not happening, right?

So, warm the engine up and set the timing and idle.

Then fix the problem you have with IAV/AAV under the throttle body and then re-set the timing / idle 'cause it won't be right after fixing the problem.

You are right, it doesn't idle high when cold anymore. Don't understand why i have to adjust the timing too, i haven't touched it. What is IAV/AAV ?
Im hopless with search, would have done better if you guys typed in norwegian

IAV/AAV is idle air valve / auxillary air valve. It is a temperature controlled valve that lets air around the throttle when cold and closes when warmed up. On early models, it's called IAV and is mounted below the throttle body and on later models it's called AAV and part of the throttle body.
