OXYGEN SENSOR HELP
 

I just replaced my Oxygen sensor (passenger side, on exhaust manifold) due to aengine code and check engine light. Also, the code reader alerts me to cylinder 1-4 misfiring. Probably due to O2 sensor malfunction. My check engine light has been alerting me to the same issues as mentioned, even after the O2 sensor replacement.

Have I missed something?

Has anyone had any experience with this problem??
Thanks.

hello there is a problem with ML cats going bad and also cracking on the cat itself. im not sure about your AMG I believe they have different exhaust, but if the cat gets bad enough they cancause misfire codes. At the dealer we found that alot of MLs that had misfire complaints were actually bad cats. just a tip that might help.
