Default Misfire and tinkle

Please help, i have owned a zt 160+ kv6 for about 3 weeks and have had a misfire. The car has been in and had the plugs replaced but the car still misfires and idels rough. The car idles about 500rpm even after the plugs
Sometimes the car is quick and other times its slower than my grannys zimmer

Also when the car is idling i can here the tapets, lifters is this normal in such a big engine, the engine only has 30000 miles on it and its a 03 car

What does your car idle at and can you here the tapets, the car come with a warrenty but there being funny as most warrenty companys are

any help i appreciated

Those are all symptoms of a failure of one or other VIS valves and /or inlet manifold.
Get your garage to replace them as soon as under warantee
