How can ut tell if the wur is bad. The car seems to be rich all the time. I've changed the fuel dist, turbo, fuel injetors, plugs,and gutted the cat. It still wants to run rich. Can ti be the WUR.

Thanks

Your model car would help.
I guess about an '81?

The WUR can be tested by performing a cold and warm control pressure test.

Why have you changed all those things? What's wrong with doing the proper adjustment for idle mixture first?

How are you determining that the car is running rich? Did you adjust the new fuel dist after you fitted it?

The WUR can only be testet with a gauge. I schould be at 2 bar when cold and go up to 3.5 bar when warm

this is a new testgauge, like the original with is N/A
