Check the fuel pressure. Pull the pump unit from the tank for inspection for corrosion and rubber deterioration. Make sure battery is fresh. If older than 3 years change it. The 30 year old eletronics are finicky. If the car runs fine now and does full power fine those injectors will give you warning later. I bought quasar from original owner with 34,000 miles. Checked all fluid levels, changed nothing and left for a thousand mile trip. Get out that oil change store stuff for sure. Drive it. Run gas thru it. Have fun.
