W126, lean right bank and rich left - Help me!!

Hello Mercedes frinds,

I changed the spark plugs this weekend and noted that all the plugs on the right cylinder bank were white and all the plugs on the left were black.

I did get a reply on another post that I did that it might be the idle air circuit on one sid that was blocked.

Well, Im clueless on how the find it and check it out.

Can You help me a bit??

Many thanks in advance,
