Tuning up my 2001 Grand Prix

I was wondering if I could actually tune up my 2001 Pontiac Grand Prix? If there are some things I can do what are they and what will I need? Thanks for the help.

Plugs, wires and K&N filter. Plugs are the hardest. But just because they are a pain in the butt to get to. I always say the back ones will teach you some new words.

Fuel filter and PCV wouldnt hurt either....~Larry~

where is the fuel filter located and what is the PCV?

pcv = positive crankcase ventilation valve. It eliminates crankcase emissions, and helps remove moisture which would cause sludge to form by routing unburned gases back into the intake manifold where they can be reburned, thus improving you engine/oil life

how would i service this and where is the fuel filter located. any other things i should do, tune up or service wise my car has 80,000 on it
ill also second was kustomkid said about learning new words while changing spark plugs, it also helps if you have the brackets off, one of zzp free mods
