Coil pack and the spark plug- check compression
Your 2000 Nissan Maxima has a 3.0 liter V6 engine , so it has ( 6 ) engine cylinders It sounds like there is a problem with the # 5 engine cylinder , perhaps an engine cylinder misfire ?
Do a compression test on all cylinders and compare findings. All cylinders should be within 10% of each other.
its a Nissan for starters but it could be the plug wires or the plugs or the distributor
You need to isolate the cause of the misfire. Could be plug, wire, fuel, injector, internal engine, etc...
