Possessed Tachometer
 

Driving home last night, I noticed something odd. Even though I was cruising at 55mph, my tachometer said 0 RPM. Holy ****!, I thought, I'm getting AWESOME gas mileage now!

Then the cobwebs of a long day at work shook from my brain, and I realized my tachometer wasn't working. At the next intersection it jumped to 800RPM and stayed there at idle. I put it in neutral and goosed it a bit, making it jump like it should... except it was odd. It'd jump to 1500, then shoot to -100, then jump to 500... for the rest of the drive home it did this, jumping all over the place.

Today it worked fine. :dunno:

I'm thinking the humidity last night got to something. Probably a loose connection somewhere. Where should I look?

If it's like my tach, there should be a wire going into the dist. it might be loose or corroded. :head:
