I have loocated a '93 V6 Camry in a salvage yard about 70 miles away. It is fairly complete. What all should I get off the car to try to fix this one?

Yes, it is possible.

Make sure the injector is shutting off mechanically, not stuck open.

You might CHK the Fuel regulator . chk your spark plugs are they light brown or black if your burning rich then leaking fuel some where (injector or regulator ) or fuel pump
