I have an 89 Accord that starts, idles around 2k. As it warms up, the idle begins to drop. It runs good for a few more minutes, then the idle drops out of sight! The engine stalls when ever my foot isn't on the gas (rather suddenly). Otherwise it starts and runs fine. Here's the list I've put together based on archive reviews. Is there anything else I should be looking for?
Things to check:

1.Check PVC valve
2.Check EGR valve
3.Check for vacuum leaks
4.Check temperature sensor (check coolant level)
5.Fast Idle valve (The fast idle valve sets the rpms around 1800-2k on startup. It has 2 coolant lines running into it. It’s on the backside of the intake plenum and has a cap with 2 screws on the top. Go to the dealer or a local parts house and pick up a new O ring for your idle screw and a new o ring for the fast Idle valve cap. Carefully unscrew the idle set screw and spray carb cleaner in it till in runs clear, clean off the screw as well. Replace the O ring then reinstall the screw. Screw it all the way in, DO NOT tighten it all the way, then turn it about a turn and a 1/2 back out for a starting point. You should be able to get a large flathead screwdriver and tighten down the fast idle valve. Its not "adjustable" per say, but I've seen it done for temp fixes. If nothing else just order a new fast idle valve for 60 bucks)
6.??
