Adjusting idle speed on stock TBI
Does anybody know how to pump up my idle? It's usually around 600-700 rpms when warm. I want it at least 900, but 1000 would be better. I don't want it higher than that. I have a 5 speed and I don't want my synchros to die.

an idle of 600-700 when warm is actually a good place to have it. if it is a smooth and steady idle i wouldn't mess with it.

Every time i put it in 1st, it synchronizes. Bigger idle, more to do.
GM left the LO3 the way it is, we still mod the engine. Why don't you run GM exhaust, with GM aircleaner, GM headers, GM Stereos.
That has nothing to do with it. I want to raise idle speed, I'll be putting in a new cam anyways. Higher idle won't hurt the engine. My friend's dad suggested it. He built a 10 second Duster, I think he knows what he's talking about. Lower idle= more carbon buildup anyways.

This same question was asked and answered in this forum last week. First try searching the database when you have questions, many times you'll find exactly what you're looking for.

1000 rpm idle for a 10 sec Duster is about right.
The carbon build up at idle with a closed loop system is mute, it's 14.7:1 at 600 rpm, or 1600 rpm
