Just to update, I got pulled away from my coupe when our daily driver 97 Jeep Cherokee (bought new) ate the distributor gear. Replaced the gear and then found cam gear chewed up too. It's turned into a nightmare with parts availability and poor quality offshore crap. I'm stumped because these AMC 4.0 sixes are pretty much bullet proof. It's been maintained since new with Mobile 1 and looks brand new inside with 175K.

I've been trying to drive the Benz as little as possible. It runs terrible. It smells and drives like a real rich carburetor does. It pops through the intake when starting.

The Mercedes shop I was going to take it too until I found the harness problem suggested trying a used throttle body. I didn't want to just through more parts at it, but as I mentioned earlier, I bought one that had a bad harness and was refunded.

So I ordered another one from AutoHubShop in Calif from ebay.
That came today and harness is bad too.

Pretty discouraging.

P.S. how do I add a signature? can't find it anywhere.

Thanks!
