Hello
I have a stock '83 engine and was thinking that the WUR was wacky. I recorded the resistance in the WUR both when the engine was cold and when it was warm and it i always 9.3 ohms. Your note says: "Example: a type -090 WUR should read 25-26 Ohms in warm ambient temps and ~9.5 Ohms when cold. If the resistance is too low, it will cause the mixture to lean out prematurely." Our temperature today when I measured this was about 20 degrees C. In the literature referenced here I did not find a reference to this resistance but did find lots of references to pressures. I am a little confused at this point. Could I still have normal pressures and yet have this apparently low resistance?

Thank you.

Dave
