Nissan Repair: 2000 Nissan Maxima Coils, nissan maxima, noticeable loss

Question
Ive been reading your answers to other similar questions about my car. There is a noticeable loss of power at certain times and the check engine light is on. I had it put on a computer and was told of a misfire in the #4 cylinder and lean banks in 1 & 2. I bought a new coil to replace in the #4.My question is which cylinder is # 4? And will replacing the coil help to correct lean banks in 1 & 2? Thanks.

Answer
Ben,

Way back when the car was under warranty there was a service bulletin on the coils.  Replace them all, the ones you have not replaced yet, and be done with it.  Check out rockauto.com and you will get the best deal.  Number 4 is the sesond one over at the back.  Basically, the middle plug.
