check the fuel injector in most cases when the number 1 injector goes bad the other injector have the tendency to misfire. Also you need to check the fuel pressure to see if is to low due to a dirty filter.

Fuel pump: The engine may crank several seconds before starting due to loss of fuel pressure caused by a bad check valve in the fuel pump assembly. (2002 models)

The plugs are probably under the coil packs, You will see a series of wiring harnesses with 3 or 4 wires in each connector that plug into a square or rectangular piece that is usually bolted down to the center of the valve cover(s). You have to remove these and the plugs are under them. Be gentle with the harness conectors and take your time as the underhood temps tend to make them brittle
