Interesting pdf the parent link was posted on wedgey forum
That dastardly throttle pot can cause that horrible stumbling people experience at light throttle
as the off idle portion can wear excessively.

I know on my old chim (well it was pretty new at the time), used have to take it out wd 40 and generally abuse the throttle pot out it back in and it seemed to cure most light miss problems
for a couple of months......must be worth knowing for the future.

That was an interesting article about throttle pots, thanks.

I have been thinking of replacing the throttle pot on my '96 Griff 500 to see if it will cure an 'engine missing stumble'. Do I need to source one specifically for my car, from a TVR parts supplier, or is it a fairly generic item that I could source elsewhere?

Thanks.

Dont forget that PDF is for the earlier Flapper type ECU fitted to the 3.5 Rovers, not to be confused with the 14cux setup the Griff's have. The throttle pot does not need adjustment as the ECU "learns" the voltage sweep on the 14cux. They do wear out as stated however.

Thanks 'V8Animal' and 'blitzracing'. Do you happen to know the LR part number for the throttle pot?
