First make sure you have no restrictions in exaust[converter] after you are sure of this check fuel pressure,this is critical to make sure you do not hurt pistons.

Symptoms Like this usually point to the Fuel pump.
Also these cars suffer from inferior wiring to the fuel pumps and a substantial Voltage drop is noted between the Fuel pump relay and the Pump harness.
The fix for this is a "Hotwire" Kit
Fuel pump kits with a Hotwire kit are available at numerous Buick performance Vendors but the best stuff in my opinion come from Racetronix,com
You should also change the Prom Chip in the ECM to a modern
Chip from Turbotweak.
This will improve driveability greatly.

SOURCE: 87 buick grand national power antenna went up, but
There is a cable and motor that actuates the antenna, the cables break on these all the time.
you can get replacement cables at nos4gn.com
the passenger fender needs to be removed to access the antenna assembly.

you don`t say where they keep breaking.if its around the bolts then you can use a thicker washer this might help.if the tracking system that the seat slides on then if there is room you might be able to weld a re-enforcing plate to the system where it cracks to stop it.
