Yes, even though the misfire is in cylinder 3, you should check *all* the spark plugs on a 2001 Lincoln LS V8. Även om en plugg kan vara den primära boven, kan en trasig plugg i en annan cylinder förvärra problemet eller vara på gränsen till att misslyckas. Checking all of them ensures a thorough diagnosis and helps prevent future issues.
