Help, With Mercedes R350
 

Hi,
I have a 2006 Mercedes Benz-R350, has 79k miles. The check engine light is on and cannot pass State Inspection. Can anyone help me find what the problem is? If it is a sensor or a part where can I find it? How can I change it?
In the bottom you will find all the information that I have from my OBDII reader!
The check engine light is on because of two codes


Code Type Status Description
P2187—PowerTrain—System Too Lean at Idle
P2189—PowerTrain—System Too Lean at Idle
Also:
Fuel System Monitor Bank 1 TID $80 - Manufacturer Defined 6 -4.5 4.5 % Fail
Fuel System Monitor Bank 1 TID $82 - Manufacturer Defined 1.1323 0.6996 1.2992 Pass
Fuel System Monitor Bank 2 TID $80 - Manufacturer Defined 6 -4.5 4.5 % Fail
Fuel System Monitor Bank 2 TID $82 - Manufacturer Defined 1.1224 0.6996 1.2992 Pass




Need help asap please! :(
