Its under the piece of plastic on top of the engine.
This is for the '05 Frontier, but should be what you're looking for. http://www.clubfrontier.org/forums/f23/how-change-spark-plugs-2005-gen-2-frontier-40507/

my petrol 04 Grandis is about to have its first set of plugs as part of its 54K service.
Changing the spark plugs on an 05 Nissan Sentra 1.8 begins with removing the plastic cover over the plugs, pulling the plug wires, and inserting a deep wall socket into each cylinder to remove the spark plugs. After each plug is removed, a replacement plug is placed into the socket wrench, and re-installed.
check your pvc valve also your coil packs and spark plugs
most likely it could be your wires going bad! or a bad cap.
Just changed plugs on my 1999 aurora and the gap was .05. It stopped a hesitation at idle too!
I have an 03 lancer es and in the owners manual it says 1.0-1.1 is the gap for the plugs
If your 05' E250 has a Triton V8, you don't have spark plug wires. Each cylinder has it's own coil, which must be removed prior to retrieving spark plugs.
Not too sure about Suzuki, but my 05 Nissan put them under coil packs that are on top of the head cover. Hope that helps some.
This is a trick question, you don't. They don't have pulg wires, they have a little coil right above each spark plug.
