Hi all, I have an issue with my 95 E320. A few months ago I replaced the infamous wiring harness. Before that the car was running rough and the CE light was on. After the change the car still runs rough, and has slow acceleration. I replaced the O2 sensor with a generic one and I temporarily removed the CAT to see if it was blocked. The CAT was not blocked at the front or back ends. I still have the CE light and the onboard diag. unit flashes 7 times. Has anyone experienced this condition and found the fix?
