Hi, I'm Mike and I'll be assisting you. Please stand by while I review your question.
Your description indicates a bad neutral connection. You must have 2 circuits that share a neutral and the result of a high voltage reading is caused by loads without a neutral which cause a high reading on one circuit and a low reading on the other. Check all neutral connections.
If on that many circuits you need to check the neutral at the panel. You may either have a bad connection on the service neutral there or outside on the utility's line.
Check the panel, all neutrals and grounds originate there.
Call the utility and have them make a trouble call. Tell them you checked the interior wiring.
The neutral and the ground are common in the panel. The service grounding may or may not be good if is dependant on the neutral. There are several was to ground a service, some better than others. Call the utility.
