Alright so the other day my car started making this faint knocking noise. It only starts doing it when its idling. Its not real loud but you can hear it inside the car. I left the car running and unplugged a spark plug as to see if the noise would stop but it didnt. So it cant be nothing inside wise like pistons or anything like that. Idk what it is? Has this happened to you?
