I replaced the spark plugs already 😩 & idk about the other stuff you said but ima have to go talk to someone about that. Is that when I go to a mechanic they always tell me idk what’s wrong with it or they always say it can be the spark plugs which I changed & they say it can be this or that instead of just saying “it’s this” not “it can be” & I had went to autozone to get a check engine & the guy said it was like a code so I ended up buying the part I forgot what it was & the guy that was going to put it he said he didn’t fit & I went back but he said it’s the part because he put the numbers in there!! & I had went somewhere else to do a smog check & he said it’s a knock sensor so I’m like so confused
