I was just driving my car a minute ago and something very bad just happened. I had a concern about my revs earlier and how it wouldn't let me go over 4000 rpm. Well, I just replaced the coil and was trying it out to see if it helped my revs go past 4000. When I took it up there, something happened and a very loud knocking noise started happening. Another person on this thread had a post about a loud knocking noise that he heard when he started his car. Mine seems to be making the same kind of noise. I need help immediately! Any help as soon as possible would be helpful, please. Thank you very much.
