2002 nissan frontier can't find the left rear spark plug after removing the wire

SOURCE: 2003 Nissan Murano Spark plug removal ( rear babk ) - the fastest way to do it.

yes i have done this myself many of times on all transverse mounted motors. also another approach you can use is to put the vehicle on jack stands and remove the plugs from underneath. then you don't have to remove the dog bone mounts. hope this helps

It makes it a lot easier if you move the alternator out of the way. some times you can get to them from the bottom of the car. When you get to the plug wires twist them to get them lose from the spark plug. Make sure you grab the end of them. don't twist just the wire.

The rear plugs on this car are relatively easy to change. First locate the electrical connectors on the rear coils and remove them. Next, take a 10mm socket and remove the bolt that hold the coils to the engine block and remove each coil. The last step is to remove each plug and install the new ones. You may need various extensions and such, but it is very do-able and you do not need to remove the air plenum as you do with the 3.5 engine used in 2002.
