Tachometer reading fluctuates
I was driving down the interstate yesterday (65-75 mph) when I noticed that the tach would jump. I was cruising in 4th at about 2100 RPMs and it would jump up to 2400, then back down, the drop to 2000, then up again. I didn't notice any surging from the engine though.
Is there a sensor for the tach that could be going bad or is the flucuating a mechanical issue? Or do I not need to worry about it?
