Having a dirty throttle body could cause you problem, but unfortunatly so could a lot of things. I'd also clean your AMM while you're at it and AIC valve, but I have no idea where this is on a 2.3l engine. I'd also suspect a vacuum leak, so read on.
Cleaning:
-Go to a parts/discount store and pick up a bottle of carb cleaner, have an old tooth brush and rag handy.
-Take a look at the engine: at the top of the engine the bare aluminum piece with the four intake runners comming out of it is the intake manifold. On the right (drivers side) of this you will see a device the connects to the intake manifold on one side and a big rubber intake hose of the other. It also has a cable going to the gas pedal. This is the throttle body.
-Simply disconnect the big rubber hose by undoing the clamp and popping it off. Take a look inside, you see the big butterfly valve which you can open and close with the throttle mounted to the side of the throttle body.
-Spray in some carb cleaner and clean it with the tooth brush, do this with the butterfly valve open and close. Wipe up the mess with the rag. It's okay if you don't get it all, but the engine might hesitate the first time you start it up.
Your AMM is located on the intake tract of the engine inline with the big air pipe at the near the front drivers side of the car. It Is aluminum with a black square on top and has a big plug coming out of it. You can just unplug it, undo the hose clamps, and pull it out. A bit easier said than done, so be careful not to pull any wires or hoses out. Simply spray it out and re-install.
Vacuum leaks:
Vacuum hoses are all of the little hoses that run fron the intake manifold to a bunch of diferent places. Make sure all of these are in darn good shape. Replace if in doubt, the correct size is 3mm and you can get new hose at a parts store. Specific problems are the "Hooter valve" which is a small black cannister near the AMM that connects to two big hoses and one small vacuum hoses. To check pull the small vavuum hose from the Y-connector and suck on it, if you can draw air the valve is bad. Also, the charcoal cannister is a problem. Remove the passenger side turn signal (very easy, one bolt) and make sure all the hoses are still connecter.
This will get you started anyway. My money is on a vacuum leak, but they cna be darn hard to track down.
