RV8 idle control stepper

[nigelj77]

Hi folks,

I've had my griffith 500 3 years now and occasionally it likes to hold onto revs at idle, typically around 1200rpm rather than the 900 - 1000 normal.

I believe supplying dealer changed the stepper when I complained about idle speed.

Do they typically only last a few years as mine seems worse at the moment, took it out and cleaned it, seemed great yesterday then not great again today?

Thanks in advance, Nigel

Thanks for the replies.

I can confirm the stepper is black bodied not zinc coloured, it looks a little different to those I have removed and cleaned and once over replaced in previous TVRs, the "plunger" on the end is silver and once I've seen before are dark grey with what looks like a chemical finish.

The car is due in for a service in a few weeks, I'll hold off replacing and await the opinion of the specialist.

For a car that sees such low miles I can't justify the £2-3K conversion work, it doesn't spoil the fun that much.

Thanks for the further information, I don't have a rovergauge and am a little worried about the running engine with stepper removed etc, I'll discuss with the specialist when it's in for service in a few weeks and see what he thinks, I can live with the cost of a new stepper but would hope they had a lifespan of more than 4K miles.

Cheers

Nigel
