Mine was like that back when I first got it and the problem was the red cloth wrapped vacuum advance line was dried out and cracked where it connected to a small thermal valve thats screwed into the intake manifold behind the throttle body...
Because of that there was no vacuum advance happening in the distributor when you accelerated.
The blue cloth covered vacuum retard hose was still working though.

It made no power that way because the stock 1987 idle ignition timing was after TDC to heat up the catalytic converter for lower exhaust emissions.
You couldn't see the hose was cracked because the cloth wrap covered it.
