When I start my 22RE, it sits around 1k idle... However, when I start going, and stop, it will sit at about 1.4-1.6k. Rev it once, SOMETIMES, it will drop back down to 1k. Other times, will just go back to 1.4-1.6k.

Any idea what would cause this?

Gunky buildup in the TB can block the air valve and cause the butterfly to hang up.

Common on 22re's.

oh and the 22re idle should be right around 750rpm.

 

Clean the throttle body and all of the vacuum ports on it, i just did the one on my 86 4Runner and it was a mess, i used carb cleaner to clean my throttle body, it works good for removing all the gunk.

 

Great info, thank you.

Thank you. I will see what I can do for that. I appreciate your help.

I tried cleaning the throttle body with TB Cleaner, took it out for a rip and the idle settled down, to about 1k. The next day it's back to doing the same old thing.. except myne is worse, around 2k.

Are there any sensor's in the 94Runner that also affect idle ?? My friend was telling me about a throttle body sensor, and that could be going , but i'm not sure.

 

There is a Throttle Positioning Sensor that I have been reading about. You may want to look into that.

 

I've never heard of a throttle position sensor hanging the throttle up - although I suppose anything is possible. Its job is to report the position of the throttle to the ecu.

Check your dashpot for hanging up - it's the disk that is supposed to cushion the throttle lever's closing. There's a test you can perform, its in the fsm:
