I just bought a gorgeous 94 E320. Super low miles and obviously very well taken care of. I do have a wierd problem however that is stumping the mechanics.

This has happened three times - never the first start of the day, but usually after I run the car 30 or 40 miles... leave it for 90 minutes or more, and get back in the car.

The car starts and idles perfectly. As soon as I give it some throttle, the car surges like crazy, like you're cutting power to the ignition or something. It has also happened while I'm going along at 65 mph. It feels like the motor just quits. I look at the tack and can see that the motor is actually still running, but no power whatsoever. I limped it into a parking lot, and it sits and idles perfectly. Try to move the car... and it jumps around, surging continously.

Two independent shops tell me the Wiring harnesses go bad in these cars, and when they do, it causes all kinds of wierd codes and happenings. "Replace the wiring harness and most of these elusive "short" type problems disappear"... so they tell me.

Well, I picked the car up today after the wiring harness replacement, and it ran great for 40 miles. Got it home and parked it. Got into the car 2 hours later... same deal.

The first time this happen (pre-harness replacement) the code read: "182 Safety Fuel cut-off switch signal for LH/HFM N/34"

This last time, there were no codes even though I was disabled with the car for over 40 minutes.

Any ideas?
