Rev counter out of sync / jumping around

I’ve been having problems recently with my Ep82 Rev counter , it would sit out of sync at 1k revs when the car was turned off and when the imobilsier was de activated it would jump up to 2k revs but would still work correctly but just display higher revs than it should. I tried taking the needle off and putting it back to 0 to see if this would do anything. The needle no longer jumps up by 1k revs when the imobilser is turned off but now instead of working normally it will only jump up or down to revs in k so if I’m going to 3k revs it will jump from 2 to 3. I had put in a new Rev counter before all of this happened and never had any problems with the immobiliser with my old Rev counter so I don’t know what’s causing this issue, any help would be greatly appreciated

The Rev counter is also from the same cluster type as my old one (mk2) just incase this helps
