2008 R350 4matic, After replacing intake manifold because of broken flap, the car starts rough idle like kicking. My mechanic checks air leaking, spark plug and coil, air filter housing and cover, secondary air pump, and other possible things. Even today I have the Xentry software and reset the mixture adaptation at idle. But still it has code P0172, P0175, and 2092&2096(the mixture in right and left cylinder bank are too rich at idle speed.) At normal driving, there is no symptom. Only at idle irregular kicking vibration happens. The self adaptation range is 4.5% to -4.5%, but mine shows way under -6%. I definitely need any experts' advice. I attach the codes from Autel bluetooth scanner. Thanks all and have a great week!
