The previous owner was trying to avoid pulling the plenum too I suspect.

Just resign yourself to the project- every single one of these cars will need injectors as they just don't last- either from age or alcohol blended fuels. If it was me personally, I would just buy new ones and change them (based on experience), but there is a good diagnostic to meter out all 16 injectors without taking anything apart. It might take about an hour to do all that.

The last time I had to work on the car, it really only took about 35 minutes to remove the plenum.
