Things just keep mounting

Who ever had this bird before me really &*^$#($ it up. The mor eproblems I fix the more I find.

Any ways My car is no hard to start when you first start it, the RPMs will go to about 1600(which is fine) but then it drops to 500 or alittle less and stalls out unless i pump the gas. It does this for about 5 minutes till it warms up. What is going on.

Here is what I have done so far

New intake gaskets
fuel injector orings
valve gaskets
reset rocker arms
cleans out lifters( previous owner left same oil in it for a year)
Distrubitor cap and rotor
Plug wires

If some one could tell me whats goin own I would be very thankfull
