The Chim was ticking over at approx 1500rpm.
Occasionally when hot it cut out.
Just taken the advice of so many of you and cleaned the fabled stepper motor, removed a thin film of sooty deposits with a cloth, replaced and it feels like a different car, just wonderful
Based on my experience, took no longer than 15 mins and can reccommend it to all, so what you waitin' for?
Thanks to previous stepper motor contributors.

Never had the fabled stepper motor probs with mine - touching wood as as I type - but why does the stepper get so fuzzy? Doesn't seem to affect Landies???

Not sure land rovers have a stepper motor do they? I thought their idle was controlled in the normal screw fashion. I think it was something that TVR added.

Ahh, that makes sense. So they added it especially to bring the famous TVR reliability down to an acceptable level!

Actually I've not had any trouble with it on the Chim, and never heard of it before on many years of happy Range/Land Rover ownership.

I understand that the stepper motor was preceeded by an adjustable grub screw on earlier V8's such as 350.
