Hello,

I notices every now and then both at idle and at cruise the tach will drop a few hunderd rpm for half a second. It may do this a few times, then not do it for a while. Is this sign of any kind of impending failure? All regular maintenance stuff including flywheel speed sensor are new.
Any tips appreciated.
Thanks,

Csaba
