Pulsing under load.. Sign In

Hey guys, I just drove my wifes car, as I was climbing a hill going about 60mph, keeping the petal steady her car started pulsing, not real bad but deff noticeable. The car was fully warm with about half a tank of gas, I didn't notice if the spedo was pulsing or not. It only does it when I'm holding the pedal steady, not when I'm giving it gas or letting off the gas. Any idea what could be wrong? Or where I can start looking? Thanks

Car:
2003 chevy Malibu 3.1

Gsxr; First thing I'd check would be the fuel filter. Did the check engine light come on?
