After this weekend and seeing what the cat and O2 sensors looked like, I am ready to buy new plugs. I did clean the sensors before inserting. I made and attempt earlier but got distracted. But I havent changed them since 2019 and that bad MAF wire was happening back then too and I did replace the MAF at that time. The problem was intermittent and even when I suspected the wire, it improved then got out of whack. I finally changed the plug and fuel trims don't go nuts, LTFT is around 2-3.0ish, not throwing lean codes.
Any suggestions on plugs? I don't remember what I used in 2019.
