    I don't want to update my old thread anymore lol
    But like I said, I pulled my plugs and #2 smelled real bad of unburnt fuel and was coated in black shit. The rest looked fine.. And the gap for all of them was .032 using a gap disk.
    HERE'S SP #2


    Im only throwing misfire cyl 2 (duh) and a lean bank 1.
    Coil packs are brand new

    Why does my plug smell like fuel ?
    Injectors or coil packs ?
    Can coil packs fail with in 2000 miles? There OEM red tops

    I've put my plugs back in with out torquing them down in the mean time

    And some say.032 gap is "optimal" for our cars. I read that somewhere on audizine.

    They can fail prematurely. Just like everything else. It's not common for it to fail so quickly but it can happen. That is with everything that you buy.
    What ever makes sense go with the opposite and you got it

    switch a coil pack to another cylinder and see if its the coil pack. if you still get the misfire on cylinder 2, check compression to that cyl.....if compression is good then test the wiring to that coil pack.

    Bought a single coil pack and swapped it to see if that fixes anything.
    Mechanic did compression and says it's Good. So he says it's injector. Can injectors supply to much fuel and make it misfire. Cause you saw my spark plug. It's coated black.
