A pinched wire behind the dash is more likely. Say you put an aftermarket radio in. Maybe it's a bit longer than the stocker and a wire got pinched. That coudl ground out the dic and cause funky readings. Or a rubbed wire, loose connector to the dic.. stuff like that.

the fuel gauge sounds like the sender (common) is starting to go bad.

Hmmm, haven't done anything to or with the dash wiring since the car was a week old. Could still be the culprit, but there's no obvious connection.

Fuel gauge sender is probably going, yes.
