My 1999 Pontiac Grand Prix has an issue?

My car as 160,000 miles on, it is a 3.8 Supercharged V6. It runs perfectly fine, with the exception of one thing: Whenever I am traveling up a hill, my car seems to struggle, as though I'm low on gasoline or something. My fuel filter was replaced not too long ago, so I don't think that's it. I only run Premium fuel it.

The struggle isn't anything huge, yet, it just bothers me because I insist my vehicles run perfectly.

The spark plugs were changed about 45,000 miles ago, as were the wires, and I keep my oil changed about every 2,500 to 4,000 miles.

So, please, help anyone?
