Emission controls on XF 4.1 carb
I'm the lucky (?????) owner of an '87 XF sedan, which set me back $800 plus a few repairs...
It doesn't go too good, so I'm fixing it up slowly, starting with the things I can do with less difficulty (& $$$). At least this one has an unleaded carb, the '86 unleaded XF I used to have had a leaded carb -- and don't you think THAT gave problems!
I've just kitted the carb, and replaced a few dodgy vacuum things, but the electronic emission controls are bugging me, bigtime. The problem is that the commonly available Ford manuals don't talk about them.
Actually, the Ford manuals are VERY lean on emission stuff -- as if they don't want me to touch it!
In particular, there's a red wire which terminates on the idle speed adjust with some fancy plastic that fits in a hole and the screw goes in that, but it makes absolutely NO electrical connection that I can detect -- OTH, if I disconnect it at the bullet, the idle does change a little. Currently it's set with the tension spring visible -- but I have this odd feeling that MAYBE the spring should be under the plastic...
Can some kind soul enlighten me, what IS this thing?
Also, where do I find the Ignition Timing Socket, and possibly the (a?) bridging plug?
