Hi everyone,
My 2008 CL63 118 KM had an issue with rich fuel on both bank 1 and 2 and another issues, after replacing the MAF, fuel pump, fuel filter, and injectors the problem is solved and no more CEL
my question is now when reading the fuel trim there is difference between bank 1 and bank 2 LTFT
bank 2 always reading -6 to -9 I know this mean it is richer than bank 1
tried swapping post cat sensor
checked all the vacuum lines although it is not possible to be the issue but checked that any way
What could be the issue, please if any one can help that would be appreciated
thanks
