Got a Zafira,idle usually a bit high around 1100, and then idle bounces around 900-1400 every 5-10 seconds. Can't see any leaks. Removed EGR and cleaned. Removed throttle body and cleaned. Sprayed WD40 around pipes to try and find air leak. Weirdest thing is it idles PERFECT around 900rpm if I turn on the air con button! Any ideas?
