    firing order help please...

    Hi,
    I'm missing a lot on #1 and #6.

    As I'm standing at the front of the car, which of the two cylinders is this?

    I'm starting by replacing coil packs for 1 and 6, anyone else have any suggestions as to why I'm missing?

    Dr. M,

    Facing the car, Cylinder #1 is closest to you on the right (drivers side). Cylinder #6 is on the passenger side and is second from the rear.

    Do you have any codes besides misfires?

    Could be many things...spark plugs, wires, coil packs, injectors, etc. Replacing everything could be costly - I would start by moving components around to other cylinders and seeing if the misfire moves too...for example put #1's spark plug to #3. And then the wire. Then the coil pack. Then the injector etc.

    Thanks Kelli, that was really the only code it was throwing except one security code from a long time ago (probably a misread on the key or something?).

    I'll try moving the coil pack and plug individually from one to another spot and see what happens.

    Thanks for the help.
