Thanks for taking the time to read this. I have a 89 560SEL that has failed the my air emissions. Before i pay for a new catalytic converter (What a SHOCK on the COST of a NEW CAT) is there anything i should take a look for on the benz to see if it has come loose or anything like that. I have the emisssions for last year and this last FAILED test below.
Many thanks for the thoughts.
