E70 4.8 misfiring

My 4.8 e70 has 2 fault codes: misfire cylinder 8 and misfire cylinder 4
I replaced new spark plugs new injectors new coils new air mass and a DME...there is no any air leak...i tested compression , tested its exhaust...everything looks perfect... At idel cylinder 4 and 8 stop working(using actual values) as i press on the gas the cylinders work properly... If i remove the air mass's plug the cylinders also work properly...WHAT IS HAPPENING? I spent all my money trying to solve this proplem..please help....And any idea about how does the DME detects misfring for specific cylinder if all electrical parts are working properly?

Do a ohm/resistance check! Continuity is only for open or closed circuit.
