Class, that sounds EXACTLY like my '91's symptoms. Had electronic diagnostics run, and they said the fuel pressure was low, probably due to a bad pump. I think the TBI's must be dependent on that constant pressure. If you've got a buddy with one of those Sun-pro scanners from Snap-On, it'll tell you what kind of pressure you're getting.
