I replaced all of my spark plugs and one of them was bent over and it still sputters around 1200-2000 rpm what could the problem possibly be

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! If one spark plug came out bent, that’s a red flag! It could be a sign of something making contact in the combustion chamber, like debris, a piston issue, or even a valve problem. That misfire and sputtering could point to more than a simple spark issue, especially if it's around 1200-2000 RPM. While a faulty camshaft sensor can cause misfires, it's worth doing a compression test first to check for any mechanical issues inside the engine. If all cylinders have good compression, then camshaft and crankshaft sensors, or even the coil packs, could be next on the list to investigate.
