look for an open vac line.
this sounds like an air leak.

Replace the PCV valve if it hasn't been done recently. Check all the breather and PCV hoses for splits. Be sure to check the hose to the MAP sensor, and the hoses under the manifold to the purge solenoid.
Could have a stuck Nuetral position switch on the trans. It's the furthest back of the two switches on the side of the trans. Follow the wire up to the bellhousing and unplug it. Check the switch for changing continuity as you move the shifter in and out of gear.

it is idling a shade high when cold, just before coming to a complete stop, it'll drop down to near 1250rpm. replaced pcv today with no changes. rpm hang when I take off without warming car since I got it, always went away within a few miles.whatever it is must have been on way out
High idle until the car is warmed up is %100 normal.
Colder the morning, the more pronounced this effect will be, the longer it will hold this sustained idle. Can make for unwanted acceleration on manual vehichles if you take off right away.

ran for a good hour, drove fast, sat in garage, was plenty warmed up. takes almost 10 seconds for rpm to drop from 4,ooo to 2,5oo. gonna start pulling vac lines tomorrow
When it's doing this, grab the IAC hose and pinch it closed....see if the idle drops.
If it does.....that's a stuck open IAC. Which means a weak "close" coil.....
So Vacuum pulls it nearly closed........but not all the way....and not quickly like when IAC works proper.
