What x and y represent? Are they non-stationary, trending? then you would get
very high R2 (~97-99%) and very low p-value. Perhaps you land on the world
of spurious regression.
In this case forcing intercept to zero would not help you. Work with
differenced series instead raw data.
Thanks and regards,
