Over Carbonation/Forced Carbonation can cause or enhance off flavors?

Hey Gang,
I was force carbing a beer and I believe it got over carbonated.  I tasted a sample and it had some wierd off flavor and I thought maybe the carbonation was affecting my taste buds.  Last night, I bled the keg and turned down the psi to serving psi.  Today I tasted a sample and it tasted fine.
Can overcarbonation/too much CO2 cause temporary off flavors?  Man, I was worried there for awhile that some infection had taken over!

Carbonic acid bite?

I think it can accentuate astringency and sourness in beers.
