Have 98 E320 Sedan. 233K...got up to 80 mph and engine light came on and backfire... able to make it home. Showing codes p0300 p0301 p0302 and p0300. Replaced all plugs and wires with proper replacement recommended by Bosch. On passenger side I disconnected coil packs one at a time and saw no difference. On driver's side I disconected coil packs one at a time and got a drop in RPMs. Switched a good coil pack and swapped for one on the other side. Still those on drivers side noticible drop in rpms. On passenger side with coil pack from drivers side no changed.

Appears the passenger side banks not getting fuel or something. has anyone experienced this? I live far out... and can not drive vehicle to a repair shop but willing to try on my own. could this be computer related

You'll find the codes in this thread

MERCEDES BENZ FAULT CODE MANUAL Online - Mercedes-Benz Forum

If you go through the PDF it says random misfires detected (ignition or injection) for the codes you have.

Has the car been sitting for a while?
