Remove the plastic cover on top of the engine by removing the 4 srews with an Allen key, you will them see the 4 spark plug cables going from Right to Left and down to the spark plugs. Grab the rubber thing the wire goes through, they will require a good yank, do not pull on the wires themselves. The plugs are at the bottom of the hole you just created.
A local garage is charging me $278-ish for plugs and wires on a 2007 Chevy Equinox today.

There is a plate on top of the engine with four Allen head screws, remove that and the plugs are there, you will need i belive a 10mm socket to take the plug wires off. This is how they are on a 2007 SS i am not sure about what model you have.
There are no spark plug wires, this is a coil on plug system. The spark plugs are under the coils that bolt to the middle of the valve covers.There are no spark plug wires, this is a coil on plug system. The spark plugs are under the coils that bolt to the middle of the valve covers.
If your looking at the valve cover on the engine you will see the the plug wires going straright in to the valve cover, obviously there are four. Those will be the plugs under the wires.
A 2007 Toyota Prius has 4 spark plugs.
Replace all the spark plugs and plug wires. If that does not solve the problem look at the coils.
Underneath the black engine cover. You will need to remove it - it has three screws. The plugs are in-line, below the cover, at the termination of the wires. They are rather deeply embedded from there.
Yes, all gasoline engines must have spark plugs. Only diesel engines do not require spark plugs.
