I'd check for air leaks first, the point is that the valve is moving so shows it to be working.

Like Tabetha said, check for air leaks, which is just a few hose's,

My escort did the same, Which turned out to be a dirty ICV, soaked mine in petrol overnight, then flushed out with carb cleaner, was sparkling like a star and worked like a gem after. No rough idle in traffic
