My C20XE is being a pain in the arse and won't idle right.
From cold it idles spot on but once the car warms up it will sit around 1,200rpm.
I can't find an air leak anywhere.
The inlet gasket is new, all hose are new and tight.
I've tried 3 ICV's all being cleaned before fitting.
2 genuine new CTS have been fitted.
What else could be the cause
