So a few weeks ago my truck was miss fireing on Cyl.#3 after changing out the spark plug and wire and the injector it went away. Then yesterday I get another Check Engine Light code that says miss fire Cyl.#5 and lean on bank #2. I have replaced all my plugs and wires, the coil pack and the number 2 and 3 injectors already but have no idea what could be causing the miss fire or the running lean on bank #2. Rather then throw more money at these problems I'm posting on here to see if any of you guys can help me out. My truck is a 3.0L V-6 with 117k miles on it and is mostly factory parts.

Any ideas will be checked out and results will be posted after completed.

Note- I have just disconcerted the battery to reset the code.

 

Im getting the same thing both the same codes and misfire in number 5 cycl. did you figure out what it was?
