Hello everyone, I own a 2003 W211 E320 M112.949 vehicle. When I drive my car and exceed 4-5k rpm, the car goes into protection mode and cuts off the ignition of some of the cylinders (p0304, p0301, p0305 p,0300). I replaced 12 spark plugs, replaced the oxygen sensor, replaced most of the ignition cables, replaced the coils, I suspected a clogged catalytic converter, so I bought and installed new catalytic converters, but the problem persists. When I discussed this issue with ChatGPT, it mentioned a faulty crankshaft position sensor or weak alternator or battery. I'm seeking help from those who have experienced a similar issue and managed to resolve it. Thank you.(i checked the fuel system there is no problem)

after catalytic converter and spark plug replacement and tried without airfilter I revved it up to 5-6k rpm about 10 times and only got a misfire error once, but at high revs, it feels like something is holding the car back, the power decreases, and it shifts gears late, meaning the car has more power at low and mid-range revs.
