Hard Idle Problem

[99GsxMD]

Okay, well when i first start my car, it has hard idles. When i start the car, it will start to idle between 400 and 600 and seems like to car doesnt want to stay on, but after i but it a little trottle and get moving it goes back to normal. I have a air/fuel ratio gauge and it tells me i am running lean at idle then bounces back up to rich then back to lean. When it first start it sits on lean till i give it some gas. I have a couple of idea's what it could be, but i dont know for sure. Any idea's?

I did a seafoam like two weeks ago, and it started like a week ago.... if that could have effected it.

Unless you have a true standalone Wideband that Gauge isnt really doing anything but putting on a light show. Try adjusting the idle screw on the throttle body to rev higher and see what happens.

The idle adjust srew has a rubber piece under it that can cause it to act funny if its busted or cracked. May be as simple as that.
