Help with tickover.

When my Griffith is up to temperature if I have to stop at traffic lights etc. the revs are high at 1500 - 1700. When cold it starts up perfectly and car runs well generally. Can anyone tell me why this would happen. New stepper motor has been fitted.

try disconnecting the stepper motor when its warm to see how it idles

Most likely a stepper motor issue or an air leak, but could be road speed sensor...mine does this as it keeps getting a signal from the speedo black box. If I turned the ignition off and on again, often it would be fine for the rest of the journey.

I still suspect your stepper motor.
You say East Midlands on your profile.
I am just outside Newark.
If you want to pop over some time soon you can try my stepper on your car, as my idle is a perfect 900 rpm. I used to have the same issue on my previous stepper, which then became temperature sensitive so was changed, but for a used original TVR one. The new replacements often give problems.

Email me if you fancy trying it.

A good way to do a check if it's the stepper or something else.

Are you sure you have the base idle set correctly? This is worth doing, have a look at the link and scroll down to . http://www.rv8r.co.uk/tickover.html

Have a look and see if the plastic plug is still in place that hides adjustments screw ....my bet is its already removed and then a simple thing to do. Instead of plugging the hose I use mole grips and two bits of cardboard to spread the pressure then clamp the pipe shut.

@OP; apoligies for going off topic

@fasterM; First of all, my 3000S won't be going anywhere without me ! I have always longed for the looks, noise and power of a Griff, but held back due to expensive Belgian taxes.

When the right one came along, I could not resist, so in 5 weeks the 3000S will have a stable-mate.

Good luck in choosing a TVR, the hunt, drives and ownership (you are entering a mad, mad world..)
