    hello i recently went to auto zone and had them run the obd2 to check for any codes & my car came back with PLENTY .. I’m learning how to fix this car as I use it so I don’t have to pay as much and so I can gain some knowledge !! But it’s getting to hectic and confusing ! These are the codes as of right now .. P0306 , P0054 , P0102 , P0141 , P0412 , P0418 ,P0443 , P0446 .. my car has roughly 190,XXX miles on it 😟 . I’m currently changing the spark plugs and just did an oil change yesterday . Need a list of the things from auto zone so I can have my car running right again !! If you guys have any answers lmk please !

    Give us a brief description of each one of those codes. There's a lot of guys willing to share knowledge, but they're not going to do the leg work.

    I would bet there's a common power circuit here. First step is check all the fuses and replace the one that is blown. Then take a look at your #6 plug wire for a mark on it where it's likely laying on metal and arcing out.

    Did a little wire diagram reviewing and everything you mention except cylinder 6 misfire has common power supply.
    Powertrain relay #40 feeds two fuses numbered 10 (Emission) and 14 (O2 SSR) in the fuse box.

    Check the relay/fuses above and that plug wirre and you should be all fixed up
    I drink..so consider that when reading my posts.
