For some reason, randomly my tach will drop down to 0... Car idles normally... and when I start to accelerate it will go back to normal.... Any ideas?

Sounds like a loose wire maybe a ground issue.
Or worse Tach gauge is going bad/failing
The tach as well as the speedometer kept dropping to zero, when the alternator went bad on my F150.
MARAUDERS get me ****!
Start with checking grounds.

Mines been doing that for 3 years
Went through the grounds
Pulled the cluster, connections were clean, guessing its my tach
It doesn't appear to be a modular component
I figure one day it'll die completely and I'll deal with it
It's all BS until you can show me the time slip!

mines been doing it for a couple months. ctrlraven looked at my grounds briefly, nothing was found, and i took apart/out the entire gauge cluster hoping to find a loose wire....but again, nothing was found. cleaned everything up with electrical cleaner spray, even a small file, and TADA!!!!...to my dismay it still fluctuates. atleast i tried.
