Cat are heating up spark and coils are new. But the diagnostics says all 8 calendars are miss firing still

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If your F-150's spark plugs, coils, and catalytic converters are all fresh off the shelf but it's still running rough and showing misfires on all eight cylinders, it sounds like your truck is playing hard to get. And if things heat up to redline only when you rev the engine, we might have a clue. Your engine might be running lean, which means it's not getting enough fuel. This could be due to a clogged fuel filter, a failing fuel pump, or even an issue with the fuel injectors. Another suspect could be a vacuum leak – these can cause all kinds of trouble and make your engine throw a tantrum. Since all eight cylinders are misfiring, it’s likely something affecting the whole system rather than individual components. So, while your truck might be new to you, it’s got a few quirks that need sorting out. If you need more advice, have other questions, or need to find a certified repair shop in your area, just let me know!
