I would start with your mass airflow sensor, take it off and give it a good cleaning. Be sure you have a good clean air filter too. Sounds EXACTLY like what my 95 was doing, took me hundreds of dollars trying to diagnose it. Finally the guy at Jiffy Lube had a look at it. (He's a rodder) and told me what to do.
I bought a new one, but DO try cleaning your first.
