Potentiometer adjusting possible?

[Marcus Oxer]

This sounds very interesting. My KE3-jectronic system on my 1990 Coupe is currently suffering from potentiometer woes. If I disconnect my potentiometer all the driveability problems (lurching at light throttle openings) go away, so I imagine (although I haven't yet had a chance to check) that the output from my potentiometer is doing something similar to what Huw has seen. If it *is* the case, Huw, is it simply a matter of changing the potentiometer? Bentley seems to imply that the whole airflow meter needs to be changed which sounds very expensive!
