My '90 idles around 2500rpm when you first start it.  Wax pellet problem?

How do you fix this again?  I've done it in the past but it's been several years and now I don't remember where to start.

If I remember right, there is a small access panel on the passenger side of the throttle body. It is held on with 3 screws.

Remove the cover.

Put a small piece of tight fitting hose on the nipple, with the other end plugged, with a screw or bolt.

Reinstall the cover.

What is happening is there is a vacuum leak. That is allowing it to suck air. The piece of hose you are using, is making a tight seal. Your high idle choke setting will not work now. It will take a little longer for your engine to warm up.

Maybe someone will provide you with the link, but this is about the best I remember.

Thanks, I'm going to take a look at it tomorrow.

Yep, you can fix it that way.  Or you can turn the thing with all the "bumps" on it that is underneath that cover.  Turn it clock-wise (in) to lower the cold idle.
There is no high idle choke setting (he is running an EFI engine).
I also thought it had to do with the wax pellet "wearing" with age.  Not with vacuum leaks, but I could be wrong.

my 90 idles really high 2500 to 3000 till it warms up and then idles fine, is this normal?

Normal?  I don't know, but most, if not all, the EFI samurai's seem to idle 2500-3K at cold startup.
I would idle it down, if I were you.  Think about it, you crank a cold engine and it instantly goes to 2500 RPM.  Not good on an engine, in my opinion.
I adjusted mine down to about 1500.
