The car was running fine. I have to make sure I don't roll over Civics when I chase down 'vettes

There was a high rpm stumble I traced to a coil wire touching a PS reservoir bracket bolt. Many wires have telltale white spots from arcing so I'm putting in a new set of wires. I'm doing the plugs while it's apart since it's at least 30K on the plugs. On a RT trip from SF to L.A. it got 19.x mpg with the cruise set at [censored] mph. Better than my 91 300SE could manage at that speed.

The French Berus look fine. If I didn't have the Bosch's gapped and ready to go I'm not sure I'd have bothered to replace the Berus based on how they look and perform. I had good luck with Berus (made where?) in a 300SEL 3.5 that had an oil consumption problem. Beru performed when Bosch and Champion were choking on oil. I understand that these Frech 3 electrode plugs might be different.

Thanks,
