how long since a tune-up? any applicable trouble codes? Your obd1 so you should be able to access some codes, yourself, as long as the check engine lite works. Use a gage and check proper fuel pressure, 40--47 psi, key on engine off. If the reading is right in the middle, should be fine. I'd probably want to check if system running rich or lean.
