Engine unstable at idle rpm
Engine when started cold is not very stable when running on idle rpm.
It starts around 1000 rpm and drops to around 800 when getting hotter, this is normal behaviour as far as I know, but in this period of time it tends to drop 100-200 rpm every now and then and sometimes it seem like the engine is going to die, you can feel the engine shake the car.
I have it sitting like this for a couple of minutes then drive it until it reaches normal operating temp .. idle rpm still a bit unstable but engine "stalls" and shaking is now gone.
Had it in for a engine test last friday but dealer says everything is just fine, but somehow I do not buy this entirely.
Car is not chipped AFAIK.
Been searching the forum for earlier posts on this subject and it seem I'm not the only one experiencing this, but can't find any suggestion on what's causing this or how to solve it.
