I know this post is old, but right on the engine theres a sticker that says use multi-ground plugs only. I read a similar problem like yours and it seemed to turn out that the spark was arcing to ground over the ceramic on the plug. So maybe it could have something to do with the single ground plugs.

SOURCE: 2000 CIVIC System too lean Cylinder 3 and 4 misfire Deteced

  1. P0171: This means that the oxygen sensor has detected a lean air-fuel ratio. This can be caused due to a vaccuum leak or a problem in the HO2S circuit or the HO2S (Heated Oxygen Sensor) itself. (Bank one Sensor one). This is commonly located along the exhaust pipe. It could also be a bad Mass Air Flow sensor or a bad Engine Coolant Temperature sensor. Diagnostic checks will be needed to be carried out to be verified though
  2. Well as for the other codes, it means #3&4 cylinders are misfiring. It is a possibility that the P0171 code mite have caused the others to show up. I can be wrong though. But it is a strong possibility. If the air fuel mixtue is too lean indeed, mis-firing will occur, unless it is an actual electronic and not a mechnical problem. By the way, when these codes appear, how is the engine's performance. Does it remain the same or behaves poorly?

If you have someone scan it with a scan tool that gives you data stream they can tell you exactly what cylinder is doing it. You might have a bad coil or wire.

SOURCE: 2006 RAV4 V6 multiple cylinder misfire, VSC, check engine and sli

You need a scanner to pull out the engine light codes.
Use a shopu manual to aid you with the diagnosis and repair.
The slip indicator and vsc light being on means these systems are not working. Once you pull the codes and do the repair and erase the codes the lights will go off.
There will be a code in there for the misfiring.
Good luck and keep me posted.

I would go with the ones autozone gave to you.then I would check the coil packs for those 2 cylinders and see if that's the problem. If that ain't the problem then I would check the crank sensor

Replace the coil packs.
Your issue is NOT the converter, or you would have a P0420/P0430 code
