Rough running 92 300CE
 

Solved my strange and intermittent problem on this beautiful car by taking it to David Poole, one of our fellow members on this site. He is in West Dallas, off Irving Blvd and his phone number is :: 469-688-0422 I recommend him highly for any Mercedes or other foreign car repair.

David quickly found that my OVP module was the cause; took it out and found that it was not seated fully -- and I have had no problems with this strange "gremlin" rough running since then. The car normally runs fast and true, with great overall performance -- but the unusual rough running was driving me crazy (as they say).
