same here... I always run my tank EMPTY, and then fill up. We're talking from ~ 400 mi per tank to getting about 220 now. At the same time, it started running like crap with the symptoms I've mentioned above. Something is definietely wrong with my car.

I'm thinking of doing plug wires and coil next, unless someone has any other ideas from me. I'm experiencing the same probs most have described here: http://forums.2gnt.com/dcboard.php?az=show_topic&forum=5&topic_id=49984&mesg_id=49984&page=

And here is the full history of my issue:
