SOURCE: How do I find and replace spark plugs, check wires

That vehicle does not have plug wires. It uses Ignition Coils instead. On top of each valve cover, there should be three square black coil packs. They will have two screws or bolts holding them in, and a couple of wires coming out of each one. You should be able to unsnap the clips holding the wiring to each coil, Remove the bolts and lift the coil up from atop the spark plug. I would absolutely recommend Factory plugs, or NGK plugs for that vehicle. Infiniti cars will not run worth a **** with anything else in them. You will think you are saving money by putting some Bosch Double Platinum or some **** like that, until you start pulling your hair out trying to figure out why it won't run. Trust Me. Save yourself a bunch of headaches and pay a little more for factory plugs. Just try not to get the coils crossed up, they are two different part numbers. I would suggest doing the job one cylinder at a time.

Horrible Random misfire in car

This is common issue with Infiniti I30 1999-2001.

When the coil packs fail they burn up components/parts on the engine computer ECU. If the problem gets worse, you will need to replace the ECU or have it rebuilt.

Is your check engine light on?
You might also get code P0505
Technical bulletin also recommends to replace
The Idle Air Control Valve MUST be replaced prior to re-installation of the ECM, or immediate damage to the computer will occur again.
Common Failures:
  • No Start, Hard Start, Engine Stalls
  • Rough Idle, High Idle, or Idle Up and Down
  • Misfire to one or more cylinders
  • No signal to the ignition coils
  • Engine Trouble Codes For Idle Control Valve (IACV)
  • No Communication With Computer
  • Replacing IAC Does Not Fix The Problem

Your question is to vague to give concrete information, but this is what I know. Every mechanic has a favorite brand when it comes to sparkplugs. Nissan people (your Infinity is a Nissan) like to use NGK spark plugs. The oxygen sensors are what controls the air/fuel mixture once the vehicle has run for about 4 minutes. Have him change the plugs and wires, and the o2 sensors and you should be fine as long as there are no mechanical issues.
