I recall it says you need to swap out the whole assembly in the bently,
although it does give precise details on how to set it up. Therefore it must
be possible to replace it, I would like to know, because when I get the code
for the pot, my 90q becomes sluggish. And as yet I have not attempted to
look into it. I must admit I haven't tried disconnecting it yet, what does
the pot actually do for us in the cis cars?

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!
