Answer
R-shod,
It's possible that it's your timing, and if you haven't had your timing belt replaced within the last 60,000 miles, it's a good idea to do so.

Common causes of the problem you're experiencing can also be due to any of the following:
Clogged air filter
Clogged fuel filter
Dirty throttle body
Leaky intake system
Weak fuel pump
Bad fuel injector
Malfunctioning ignition component (spark plug, plug wire, distributor, coil, etc.)
Malfunctioning intake conponment (throttle position sensor, idle speed controller, etc)

Your car may just need a tune-up to get it running properly again.  Have your mechanic inspect it for further diagnosis.
Good luck!
