check the caps and rotors for tracking, clean them and scrape any corrosion from the posts and rotor tip. hows the fuel pressure? got a stuck open or leaking regulator? look for fuel in the vacuum line. does it hold vacuum? same with the egr valve. broken or cracked vacuum lines. stuffs gettin' on in age.

It doesnt have caps and rotors. It's an electronic ignition system, using coils. All the fuel system has been checked with and no issues found.
Its just so weird..
