    Have a Check engine light, got it scanned and came up with 4 codes.
    o2 bank 2
    miss fire cyl 1
    miss fire cyl 4
    and cant remember what the 4th was.

    It runs fine and havent had any issues, but I'm sure it'll run better and more efficient if fixed.

    Any ideas on what the miss fire could be? I know what the o2 is (did a cat delete)
    Also with the new exhaust and cat delete is my car tuneable?

    well now the CEL flashes at me every so often. Talked to a few shops about tuning, that said cant do nothing with the older cars. Needs to be 00 or newer :(

    Anyone know how to do this, other then swapping everything out or getting a stand alone?

    well did wires and still code. The miss fire is for cyl 1 and 2. Looks like the coil pack is actually 2 in one. 1,2 for one side and 3,4 for other.

    It sounds like it has a rod knock at higher rpms, friend said its the miss that I'm hearing. When I first start it up it does it just for a couple seconds then goes away. idk what it is or could be.

    Coil packs are per plug, they don't share. And cylinder 1 and 3 are one side, and 2 and 4 on the other side. I would also pull the plugs and make sure they aren't fouled at all.
