2000 ML320 with p0301 p0302 p305 ???

I have my ml320 and its been running on and off from good to bad, but lately its just been getting worse. Its been throwing p0301 p302 p0305 and p0300 every now and then I scan it and a random p0304 or another misfire will come up but for the most part the its been cylinders 1-2-5. I have already replaced the MAF and im not to sure what it is ?


anybody have ideas?

It appears you might have a catalytic converter problem. Probably part of the substrate has broken off and intermittently blocking the exhaust passage.
