Idle low

Earlier someone had an idle that was to high, Well i have an idle that is to LOW
what I have is a 89' f250 with a EFI 460 with a TFI ignition and I just recently
did a tune up and replace the O2 sensor, It seems now the IDLE is to low say
below 400rpm's I believe it should be around 600rpm's or slightly higher, anyhow
is there a way to adjust that idle up? Oh and I also think the timing is correct,
and prior to the tune up it seemed to idle alittle high, or maybe just right.

Either the IAC (Idle Air Control) valve is bad, not connected or you have a computer problem or the Spud connector cap is off.

this may help on my diagnoses after i check the above,
when its warmed up and idleing low i will put it into gear (auto)
and the idle will increase then drive awhile and go to put it in
park and it will almost stall or stall. and what is a spud connector cap??

The spud connector is the shorting cap on the ignition system that takes the computer out of the ignition timing control ad gives you base or if you prefer initial timing only. This will drop the idle drastically.
