Sometimes in these cars around your age the fuel pump is able to produce adequate fuel pressure for idle, but not able to produce enough volume for driving conditions. Checking fuel pressure while accelerating in gear to full throttle will show a fuel gauge that drops from 55psi down to 40 or below. It can also be monitored using the rear 02 sensors if you have a scan tool
