Factory Tach reading funny
The factory tach in my 90 IROC shows higher engine speed than what the engine is actually turning. Any ideas?

It's actually a fairly common problem. There's a thread or two about how to fix it on the interior board I think... It involved some dissasembling and soldering, though.
But if it makes you feel any better it's not uncommon.
