Hey all, I just picked up my 2nd MN12 SC yesterday after a threey year break(previous car was 1990 XR7 AOD). The "new" one is a 1990 SC with the 5-speed. Couple of things I noticed while driving it home.
1. The speedo is about 6-7 mph fast. Granted, I would rather tell me I was going faster than I actually was, but It is pretty annoying having to subtract 7 mph from what it is telling me.
2. Tach Doesnt work. It just sits at zero. To go along with this it starts "occassionally". As in, it starts every 3rd time or so. From reading on here that sounds lioke a bad cam sensor. Allthough, I have skimmed the recipts that came with the car and they had replace the cam senson, crank sensor, and harmonic balancer 2 years ago. The upshift light does not come on when cranking either.
Could the problem with the tach be in the gauges?
Thanks in advance.
