WUR....what does it really do?

Well at this stage in my Fuel issue saga....im starting to wonder what the point of the WUR is??

So I attmpeted to drive the car again, and all seems ok at first (running with the O2 disconected) its "driveable" but last time, I went to a friends house, and car was parked for a couple hours, came back and car barely starts and is barely idling, the A/F is 19-20+, Im thinking the WUR has heat soaked, so I enriched the mixture and drove home.

about an hour or 2 later I said, lets see what happens, So I try and move the pin(richen) the WUR... but it doesnt get any better. Then I swap WUR, with a "cold" one and see, sure enough it runs in the "normal" AF. Ok great....Next day I think its fixed and I can go for a drive up to the mtns. I drive and seems ok, I park for aboout 30 min, come back.....and guess what? A/F is way lean again!!!!

W T F!!!!!


So what if I take the "warm up" part out? I should be able to start it, and then set it. with out the WUR changing things. as it heats up.
