Default Tach drop

Ok, posted this a bit ago but and or so WHAT makes my tach or the se tachs drop down to about 200-300 RPMs when sitting still in park or D? There seems to be no stumbling of the motor just the tach reading low.....
I have tried the turn key to run position press all the way to floor slowly and let return slowly then turn key off.. No difference seen. any helpful ideas or is it just something ewe learn to live with...?

I am having the same problem with my 2006 1500 V-6. The tach just drops to almost nothing and then goes back to normal when you start off again.

yes exactly but I have yet to notice that the motor actually runs at that low of RPMS ... Seems to be still idling just fine. sometimes it will drop and then return to normal 500 or so on my trk.

The engine seems to idle fine at the proper rpm but the tach does not indicate the correct rpm. I checked the electronic connections but found them tight. Does anyone know if this goes through the computer somehow?
