I’ve got a 2016 with the 3.6l and around 130k miles. It began misfiring like two years ago, but didn’t throw the engine light until last week. Took it in, needed all spark plugs replaced. Get it back and it’s running better than it has in YEARS. Great! Next day, I start it up on my break and it’s shuddering bad again and the engine light is back on with the same cylinder misfire. What’s up with that?

Hi, I’ve got 19 rolls of 25 ISO slide film and am unsure how to shoot wildlife at that speed. I typically handheld shoot using 50 ISO, and that barely works. I know decades ago people shot wildlife on Kodachrome 25, so it must be possible. What are some tips you guys have, and what should I expect to be unable to do at that speed? Edit: Lens is wide open at f5.6
