05 & 06 350es read anywhere from 0-20 mph(depending on rpm)when standing still. Also having problems with idling. backfiring and performance in general. Most of the forum agrees that the idling is a bad fuel(dirty carb) issue, but I'm wondering if the 2 issues are not related somehow. Both machines have less than 300 miles and are used only 4-5 weekends/year. Haven't heard of anyone else with the speedometer issues.
