Where are the spark plugs for an 05' Pontiac Sunfire?

[Serena]

My Sunfire has been losing energy lately and I am assuming that it might be the spark plugs malfunctioning. Where are they located in the engine and how hard would it be to change them out?

Energy as in how ?

Hp?

Or

Electrical I can answer both of them ..

If its in hp it can be alot of things

Oil is old
Transmission fluid is old.. It can be your spark plugs but i doubt it its an 05 ..

if its electrical your battery is messed up or your alternator is not functioning as it should be if this is the case then you should go to autozone so they can check the alternator for free ...

Unless you have a *flashing* check engine light on your instrument panel, then your spark plugs are fine. Maybe check your air filter and see if it is clogged.

If you have never changed the fuel filter and air filter and you have more than 30,000 miles replace them.
