What am I missing? (Spark Plug Problem)

[takrdown]

What am I doing wrong?

I just went to changed the spark plugs at the 90k point (the dealer did them at 45k) and when I went to start the car up after I changed them out I got multiple misfires from different cylinders...mostly 1 and 6.

I followed the DIY on the site, torqued the plugs to 23nm, and made sure the coils were well seated. The car ran perfectly before I started.

I bought the OEM spark plugs from BAVAUTO and verified that they are the exact same as the ones I took out. I've even gone as far as swapping coils and putting in the old plugs but that has fixed nothing.

Any ideas? Thanks in advance!

Move the coil packs around and see if the misfires follow them...they might need to be replaced. GL

Thanks. I tired that earlier and it did not follow them around. I would hope that with them working before I started the swap out, they would work after the swap out, but this engine does some crazy stuff.

An update (not good): I just reseated/reinstalled all of the new spark plugs, retorqued them, and reseated all of the coils and tried to restart again. I threw a specific misfire code on 1, 3, and 6 and then got a multiple misfire code thrown. This is so frustrating. The car worked fine before I popped the hood.

Did you look at the bottom of the plugs before you put them in...may have been dropped and/or damaged? Did you use anti seize on plugs, heard that is a NO NO.
