A160 -99 Engine knock, missfire and error code P0340


I have a problem with my A160 -99 and getting really tired now. So I need some help please.

Symptoms are:
-Engine knock in a few seconds after I start but decreases after
-When the engine is warm, it goes worse, jerky at the gas pull and strange rattling sound coming over 2000rpm.
-When it is warm it starts to missfire on idle.
-Also got the error code P0340

I have changed to new ones:
-Spark plugs
-Plastic Ignition Module
-Timing-chain tensioners

What could it be?
