Need a good working one.

On cold start up my revs hold at 2k until warms up then its fine.

What revs does it do with the blue temp sender unplugged? Often worth checking for air leaks, and that the idle screw and ignition timing are set correctly before replacing the ISV. You can also re-tension the springs in the ISV too if they're opening a bit too much when cold.

I have a working one which I took off my car as I no longer run one.

Havent unplugged the blue temp sender yet. Will try this tonight.

Havent altered the ignition timing since it was mapped but might just need tweaking, and i spent sat morning tie wrapping all the vacuum pipes as the ecu feed one popped off at santa pod. There should be no leaks at all. The only one i need to check is the one from the ISV to manifold.

My air fuel mix is running slightly lean as well, if that has anything to do with it?
