I have a 2000 Toyota Avalon. It started misfiring last week, this is like the 3rd time this year. They just swap the spark plugs and it seems to work fine for a couple months then BAM! Misfire. I’m stumped:

    There is a lot more to misfire than swapping plugs. The root cause is something else. Find another shop.
