Have you pulled out the spark plugs to see if there are any tell tale signs on them.They are a good indicator of many problems that occur and can save a lot of time isolating the problem.They should all be the same colour.Is the air box and lid properly secured with no leaks or splits in the intake tube.Have you put injector cleaner in the fuel tank to clear up any possible dirty injectors.Therse a few things your problem could be including engine vacuum leak which you can find by lightly spraying carburettor cleaner around suspect places such as inlet manifold and around injector seals.

I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

i guess it has carbs on that year, which means
1.your main jet is blocked or
2. fuel filter is clogged,
3. fuel pump worn out
4.blocked fuel line
you simply have just enough gas to idle but when you demand more there just is not enough,
