Speedo/ODO help

[KDAWG97M3]

Ok, so I have swapped clusters, changed odo gears, correctly, and have even taken aprt to do it again...so here is my issue
My speedo will work sometimes, not all the time, when it works, it will work for a bit, then spike the stop...my Mpgs wasn't working, now is...my coolant guage works..gas is quirky?? Now the kicker the odo doesn't work (gears replaced).it won't collect mileage??

I have check the diff sensor..the prongs looks brand new, the connector as well?? This is m20 325ix?? Any help would be great...thanks

Are the service indicator lights working properly? Sounds like your SI board took a shit.

Failed to mention. They work just fine.

Replace fuse 10, 12, and 21 first. If your speedo and odo fail at the same time, the problem is most likely fuses or speed sensor connection.

SI board doesn't have anything to do with the speedometer

do you have a 13 button OBC?
