Good day everyone,
Yesterday as I was driving to the store, I got a CEL and reduced power/jerking. Got home and checked the code and it was P0324, knock sensor. I don't know if it's coincidence but I added 80z of Seafoam high mileage to the crankcase and the remaining 8 0z to the fuel tank at 3/4 full (total of ~75miles traveled) as I planned to do an oil change today which I already did. After the oil change I started the truck and decided to take it around the block, no CEL and tick is still present. I did notice that it went away as soon as V4 mode engaged.
Am I looking at a collapsed lifter? Tips on what I should do on my own before I take it to a shop?
Located in Houston, TX if anyone has any recommendations on a reputable shop.
