No fuel leaks that i can tell and ive spent quite a bit of time under the car so i assuem i would have noticed.

Idle control valve has been cleaned and if it is unpluged the car will die.

Is your evap system for the fuel tank breathing properly?
Are all the gaskets on the intake manifold seated proper?
Not Sure? Pull/push gently on intake manifold.. look/listen for idle RPM changes..
Throttle Position Sensor?

^^ for all that stuff i have absoluty no clue
Find out.

Inspect, check, clean, the throttle position sensor on the side of the throttle body.
Inspect, check, and find out if your intake manifold is leaking.

Check engine temp sensor also.. If it works.. you'll know.

There is a tiny hose on the fuel pressure regulator that tends to crack over time.
It attaches to the under side of the intake manifold and its very possible a leak in that tube would not be detected.

Vacuum check..
-intake boot to valve cover
-intake boot to ICV
-ICV to manifold
-manifold to FPR
-manifold to brake booster
-TB to charcoal canister
