This is a day late and a dollar short, but here is my story.

I had a problem just like this, tried troubleshooting it myself.. took it to a mechanic (who had it for over 2 weeks) that was also unable to fix it.

I replaced the fuel filter, had the ECM tested, and did as much research as I could.

In the end it ended up being a rusty post on one of the coil packs. Its an easy fix, and cheap to boot. The coil packs are located on the firewall (on a 97 anyway). Make sure you either mark your plug wires or take them off 1 at a time to check, or you could have a heck of a mess.
