any ideas on why? bad ground?

 

Its probobly wiring issues, could be in the dash or multifuction switch.

I love your name. LOL

 

your signal bulbs have too high of a wattage and are over-heating your car when they flash.

I've seen it happen!
just kidding, but seriously you know it's gotta be an electrical issue. Your temp gauge is analog though, right? Does this happen when you signal left OR right? Maybe one side has a short.
Do your blinkers on both sides blink the normal, slow, pace? Or are they fast blinkers - like maybe a bulb is out (sidemarker maybe)

 

thanks for the help guys (I especially like the overheating idea ), it is an analog guage and I will have to check if it does it with left and right signals, it does not do the fast blink thing,

wow, i got the only positive comment on my name so far, usually i get yelled at for my name, one person has said my name is ruining honda-tech , others have said it is way too long and annoying and i need to be banned

 

Try to find the wire that drives your temp gauge. Under your dash/cluster might be a point where that wire and your signal wire are interfering. OR, somewhere along the length of the temp. gauge wire - grab a manual and see if you can trace it.
