First thing I'd check is spark plugs and plug wires -- those are pretty classic symptoms of a four-cylinder engine that has only three (or two) cylinders firing.

There are other things that could cause that, too, but eliminate the simple stuff first.

If plugs (check gap and condition or replace), ignition wires (replace if they are old), and coil towers (they can get corroded causing mis-firing) check out OK, then remove the air induction duct to the throttle body and clean the throttle body thoroughly with a good throttle body cleaner, old toothbrush and soft rag.

Also if that does not help, then verify that all the fuel injectors are firing properly. A can of good FI cleaner can help open the injectors and improve delivery/vaporization.

Visit any Autozone store and have them read the codes - people here have stated that they do it for no charge. My guess would be a sticking idle air control solenoid in the throttle body. But don't start spending money and replacing parts based on guesses, get the stored codes read first to see if they tell you anything.
