Hello Scotty,

I change the head on my vehicle but I'm having this loud engine issue, could it possibly be my spark plugs, I've never done a tune up for this I'll attach a video, really need your thoughts, I hope I didn't scammed from this mechanic...



could be lots of things, go to another mechanic and let him listen and check it out

I forgot to mention I have a tool that stated p301 misfire in cylinder although I haven't changed spark plugs in about 7 yrs
