Guys...just an update on this thread. For the last two days I've been able to get my car running as good as it ever has ('91 300E 185K miles) . I put cheap copper plugs from Auto Zone in (after I tried Bosch Irridium +2s that fouled right up and killed the engine and left me stranded) and adjusted the Lambda CCW to until it purrrred. Now, it accelerates on que, has solid power, and idles like it's off. I need some new suspension parts, fuel accumulator, and a few other things (cosmetics) but I feel like I could get this thing close to how it use to feel when new (well, I'd need new seats too but gonna try padding them up). Anyone else out there get to where I'm at with this car that ran bad and now feels pretty good? Hope this lasts for a while. I need it to.
