idling weird any suggestions?

[tonyd21]

So I got a 93 Ka24e automatic hardbody. My problem is that when I come to a stop my trucks starts "shaking" if that makes sense. my truck idles from 1000 down to about 500 or lower and it bounces a few seconds before it gets back to normal idling, I usually put it in neutral or give it a little gas and it stops. Im thinking its my idle air control valve? but i cannot locate it i know its suppose to be by my throttle body but no luck. I was also thinking maybe its my tps? Any suggestions would be great! Thanks in advance

My 89 does that also. I was told my egr was leaking.

[tonyd21]

have you replaced the egr?

[longtooth]

Nope. Unplugged it and it helped out. I have a new one I just have had too many other projects going on.
