Please provide the wire and stripe colors; with those, we may be able to identify the valve function.
They are Red and GY/YL. But, I've discovered a mystery here which may be more solvable by you guys who have much more experience with Fox/SN95s.
While I had the upper intake off, I noted the vacuum hose going to this solenoid looked pretty maggoty, and had a splice in the middle, to boot, so I replaced it. Look at the pics I just took, please.
It's tucked down inside the loop of A/C pipe, it's electrical connector down below. The RH hose goes directly to manifold vacuum. The LH hose, very rough looking, if touched, the fingers come away covered with Carbon Black, the hose disappears into the area between the fender splash shield, and inner fender well. This is all RH side at firewall. Doesn't look at all like Ford placed it there, to me.
Here it is pulled up out of it's hiding place. It has no markings of any kind to identify it, as a Ford OEM part would. I removed the connector, pinned it connected to my VOM, had wife turn key on. I expected this thing was some kind of vacuum controller for the climate system. WRONGO! 12 V present key on, no accessories on.
I took off the crummy looking fender-hole hose, attempted to blow through the valve, it's closed, no surprise. Then I SMELLED GASOLINE! Very strong smell. My guess is they connected this hose to the vapor line from the tank, and whenever the engine is running, it is pulling full engine vacuum on the TANK!
Do ya think I've found the cause for this thing getting 14 mpg best? The engine is forcing evaporation of the fuel in the tank constantly, and burning that evaporated fuel! No problem for the tank, as the fill cap will allow air into the tank to it's usual limited amount. Or, under 20 inches of vacuum, maybe gas evaporates at such a rate that NO air enters the tank to speak of, or very little.
What do you guys think of this find? What would you do? Remember, the canister is gone, it's solenoids are gone, wiring to them nowhere to be seen, without tracing back to PCM, nylon vacuum tubes plugged and taped-over. Thanks fer readin'! imp
