I have noticed a slight miss / roughness at idle in the Typhoon. It was only just noticeable until I took in in a couple of weeks ago to Ford for the 45k service. They reckon that a hose clamp was loose causing a boost leak was the problem. Boost at idle? They flashed the Computer to the newest software. Now the idle is worse. Any ideas what is could be? I think I need to find a decent mechanic to work on the thing in the Western Suburbs of Brisbane. Jimmy
