W124 M104 Poor Acceleration
Hi everyone!
As you can see in the video, my E320 is pulling like a tractor. It gets worse at higher speeds, but I couldn’t upload a longer video.
I’ve replaced almost everything—new Wiring Harness, OVP, MAF, spark plugs, O2 sensor, filters—but it still runs terribly.
The only thing I can think of is the catalytic converters. Could they be blocked, causing poor acceleration?
Any ideas would be helpful! I have a feeling it’s a simple fix, but I haven’t been able to pinpoint it yet.
