EGT gauge on the fritz??

[Noam]

Is it normal for my EGT gauge (autogauge) to spend a few seconds at 200C degrees after being warmed up? . I'm talking being in traffic and slight throttle blips (kind of floding and cooling the engine at that, as I'm with adjustable FPR).
High speeds - no problem .
I know idle is 350-400 usually celzius degrees .
I get that usually , but it can fall to dead 200 all of a sudden .
Is rich mixture causing these sudden drops at idle? could they?
Thanks for any input

my sensor does'nt register until >200'C on the zeitronix.
did it do this before or is this a new quirk?

Mine's also only from 200 c
Brand new gauge .
Didn't seem to do it that drasticly.

once warmed up mine wont drop to 200'C at all.
400'C when warm and running

if yours drops to 200'C at moments i would hazard a guess a connection problem.
