3sgte idle Options

[supra12big]

I have been trying now to almost get the most perfect idle for my 3s, its bascially there, but it jumps very slighty sometimes, i have it a 750 sitting near perfect most of the time, but i want to know what makes it jump up to 800 sometimes or even a little more then that, i have done timing, cap and rotor, plugs, wires, fuel filter, air filter, anything else can someone say to help my idle be perfect, thanks what are key things that make the idles perfect?

Have you got the vacuum pipes that run down the back of the engine to the power steering pump?? the often go brittle and crack. I wouldnt worry much about a 3sgte hunting a bit on tickover, you`ll be very lucky to get a spot on tickover.

No as a matter of fact. I tugged on them to see if I could get the idle to drop and nothing but I should go ahead and replace them. Where do they go on the power steering exactly?
I know exactly what you mean about the hunting but this can be a bit more pronounced [sometimes as high as a 750RPM increase - especially when the Turbo timer is engaged]. When it's just hunting after idle down or whatever it just comes down rather slowly but hits a specific idle and wont' vary most of the time. What gets me is the idle can be diff each time sometimes and act perfect other times.
