Hey, today the 312R tach needle no longer is rock steady, now shaking a bit at various RPMS, but really acting nervous between 4 and 5K RPMs. Searching the threads here there's some old posts about this being somewhat of a common occurence and how replacing the tach has solved the situation with some. Others just live with it as Italian pizzazz. Any updates or new information about a nervous tach needle? Anything I can look for or note to the dealer? Today was a hot temp day, but not sure this has any relevance. Thanks for any info.
