1998 Mercedes-Benz CL500
Ok guys here goes, I drove to Vegas last week and my on my way back my 98 CL500 suddenly went into stumble home mode and the check engine light went off and eventually started blinking. I thought it was the transmission at first so I took it to a shop that ran the codes and it came back saying the all the cylinders on the driver side are misfiring. I had no choice but to drive it home and on the way the car ate all its oil. Now today I replaced the spark plugs, to no avail. Next I switched the ignition coils around to see if it was possible that 4 of them were busted, they weren’t, again no difference. Then I replaced the cam shaft sensor, to no avail. As it stands now the codes still read misfires on all the driver side cylinders and I’m out of ideas. Also I can hear a loud knocking coming from the bottom of the engine. (Sounds like crank shaft… God I hope not.) Also did compression test and compression is fine. And ideas?
