2015 ML400 4MATIC misfiring
Hello everyone, I need help. I have a 2015 ML400 4MATIC. It has 86500 miles. It’s having multiple random misfires. I pulled codes P0300, P0304 and P0305 (permanent codes). I changed all spark plugs and ignition coils. It’s still misfiring and showing same codes (permanent codes). Engine runs shaky and rough very noticeable when idling(check engine light flashes when idling or going2-5mph), also it seems to be getting worse the longer it runs at lower speeds. When pressing gas and going on higher speeds, it acts fine (check engine light is present but NOT flashing). However there’s a very very minor shake when driving.
please let me know if you had a similar issue and what to do, thank you.
