Just want to know what everyone idles at when they are warm? I think my idle is set to high---around 750-800 when warm. If so , can i adjust the idle from the idle pin and where is it located?

Thanks

Ps--You guys have any of you vaccume lines capped off? I got mine back with some of my capped off.

There is a gold screw right next to the intake manifold that you can turn to adjust idle.

I have the charcoal canister(or whatever you call that crap) lines capped. My engine rarely idles under 1000.

750-800 when warm is normal.

If 750 is high, where the hell do you want such a small, low compression engine to idle?

I need to get some pics up but one of my lines capped of is a vaccum line underneath where my BOV hose runs from, and one that is just open (nothing connnected to it) is underneath my throttle body....

better block off that one under the TB, you will idle high if its open to atmosphere.

my car idles at 800rpm when warm. if i try to set it lower, the idle doesnt stay steady and stumbles after revving the engine or coming to a stop.
