for sure, i'd make sure i took it to a "test only" station, but when the
op "witnesses" a number of things that are clearly wrong:

"i do not remeber testers ever having trouble getting a good tach
reading in the past. They always just plopped that paddle up on the dash"

"RPM............2718" vs. "i peeked in at the tach which up around
5000-6000"

i seriously doubt his story.
