The flat tappet cams were an Achilles heel on these 1987 TBI engines. They would wipe cam lobes, and then completely defy any attempt to get them running correctly.

I suspected and/or knew about three problems with my '87 TBI before I ditched it. Wiped cam lobes, plugged catalytic converter, and corroded electrical splices in the engine wiring harness. Resolve or rule out those three issues, and you should be good to go.
