That is the canister purge solenoid. I tried to get a used one but it was hosed also. It purges gas fumes from the canister after starting your vehicle...it is good for the environment for it to work. You can plug the hose and leave it connected to the pcm (won't throw a code), then get a new one when you can afford it. BTW, everyone including FORD had the wrong PN for it, the right one for my 90 is E6ZZ-9C915-A the box also had CX-1158 on it.
