My Corrado VR6 was having iddle issues, I cleaned the ISV out with carb cleaner, but now it seems to be sticking, Some times the revs stay to high at idle. and some times it runs too slow, almost stalling at random gear change moments. Is this a fubar ISV. Or should I have lubed the ISV after cleaning it?

My guess is that the carb cleaner ate any lube that was in the valve.

What would be the best thing to lube it with?

I was advised back in my GTI days to clean with petrol and specifically not Isopropanol to avoid damaging the valve...

I always use carb cleaner on mine and never had issues.

Does the car only try and stall when the engine is warmed up?

Yes, And this has only happened since the ISV and throttle body was cleaned out?

Try taking a spark plug out and see if the car is overfueling.
