I did a search and some reading but there was no solution posted. The tach in my 90 is intermittent. Sometimes it works good, then it will just drop to zero may or may not come back. sometimes it looks like its trying to come back and tries to creep up to 500 or so. No check engine light no codes. is there gears in the tach? I have never had one of these clusters apart.
