This just started happening about an hour ago. I was driving and the tach seemed to be reading about 500-1000 RPMs higher than the engine was actually working. In second gear, the needle is usually fixed at 2K when I'm travelling 20MPH, but now it is around 2.5-3K when I'm travelling 20MPH. The first turbo, which usually kicks in at around 3RPM now kicks in at 4K. If I wasn't looking at the tach, the car would feel as though it were driving correctly but it is as if all the numbers on my gauge have shifted clockwise. I have no clue what it is!

 

As you may already know FD's have been known to have problems with there tachometer.

 

So this problem is not suprising to anyone? In that case, I guess there is nothing to worry about right?
