M50B25 idle problem

I've had this problem since I bought the car. When I start the car cold it runs idle pretty well and stable and doesn't smoke, but after few minutes rpm goes down a bit and it starts running so bad that the whole car is shaking and it's smoking quite a lot it seems to start running on rich for some reason? So far I've changed new bosch lambda, new sparkplugs, new camshaft position sensor, checked all intake hoses for any cracks and leaks, cleaned icv and tested that it's working and also tested ignition. Still no any diffirence. Got any ideas what to do next?
