I have bought new spark plugs and will put them in ASAP. Any other suggestions, ideas?
Also - I love my car but have noticed the brakes always feel soft and when I am slowing down I can feel the brakes....not knocking or anything, but almost like the brake pads are warped or something, but when I have had brakes checked they are fine.
I welcome any ideas. Thanks

Welcome o the forum. I guess that is around 100,000 miles. Definitely change the plugs. Ngks or ac delcos are my favorite. No platinum plugs.I would recommend some pm at this mileage.
Air filter
fuel filter

check the cam/valve cove gasket for leaks. When you pull the plugs are the wire boots oil soaked. If so replace gasket
replace the coolant temperature sensor with the updated brass tip design from saturn if it has not been done already
clean the throttle body,IAC valve and port, EGR valve and port.
Spongy brakes need to be bled. If you feel a pulsation in the pedal as it is applied the rotors need to be replaced or machined.
