Hey Scotty From Scotland UK. I know your not a fan of mercedes but my 2004 mercedes c180 auto 1.8 has been throwing codes on my obd2 scanner and it points to the MAF sensor or possibly the O2 sensor Would this problem contribute to sluggish shifting in the transmission. Thanks Scotty.

yes it would, and mafs often go bad on those if you want a guess

Sorry scotty didnt get what you meant at the end there ?
