Pyrometer needle jumping

Anyone ever seen this? I wouln't think it's the ground since all my gauges are grounded together and only 1 does it. It doesn't do it all the time either. It's very random. It just started about a month ago. Doesn't matter whether it's hot or cold outside or how high my egt's are.

I've had it apart and checked the terminals on the back of the gauge, they're tight. Checked the ground and it's good. Got under the truck and made sure the probe was tight and it seems good too

Eric,

More than likely its the gauge I've had several autometers do that. one time i had a guy that didnt put the shrink wrap on the pryo connections on under the hood and it caused that also. From my experience since it doesnt do it all the time its the gauge though!!!

2005 F250 ext cab 6spd 4x4 all stock for now!

I shrink wrapped the connections and even arched them so water couldn't get in the shrink wrap and set. I assume if the gauge is screwed, I have to buy a new one?

yeah your pretty much goin to need a new gauge!!! How long have you had them??? I think autometer has either a year or 2 year warranty. your best bet is to contact them.
