Currently the codes on my car P0301 for the misfire and only a couple days ago I had C1201 pop up for the ABS system, I don’t have an ABS dash light on though. I’ve cleared the codes many times before and P0301 always comes back and has always been a permanent code since this problem began. After working on the spark plugs, the permanent code is gone, which makes me feel like I fixed something.
The last thing I did was check the spark plugs, the one in cylinder one was a different model than the other 3 and was gapped way too small. I fixed the gap and then swapped it around to cylinder 2 to see if it was the spark plug, so far no. I plan on replacing the spark plugs soon anyways.
I have P0134(front O2 sensor no activity) disabled from popping up, couldn’t fix it and read on a bunch of forums that it’s common if you have catless headers and it’s ok to disable.
P0140(rear O2 sensor no activity) popped up last week when I swapped tunes to see if my tune was causing it. I’ve found that to be common whenever I change tunes and it disappears in a day or two.
