These cars were the first SFI motors, but they used the old stupid computer. Sensors, connectors and grounds are the biggest issues with these cars. Garbage in equals garbage out, with ALL computers.
Timing gear is a big deal, they dry out and crack/disintegrate with age not just miles. Sensors and connections too.
I would change oil often for a while so the fresh additives can work their detergent action on the interior parts that may have corrosion or shellac on them. It's cheap insurance.
Look at the fusible links at the starter, they use rubber insulation on them so if they get hot or melt, they will stink as an indication of problems. BUT that insulation dries out and cracks and falls off and can cause a short.
