Engine misfiring and not accelerator properly

Greetings to everybody. I have a problem with my car listed above w203 c240. when I start it, it struggles to accelerate for some minutes around 10 minutes after that it will start responding when I press the gas pedal at this point it will be in park when I put into drive or into reverse it won't accelerate again but if I put it in park or in neutral it will respond and rev. so, I hookup my laptop to scan it it's showing misfiring on cylinder 1, 2 and 3 and showing about catalytic convertors and O2 sensor it's not talking anything about throttle body or accelerator pedal sensor.

So, what I have done for now on misfiring I bought all twelve spark plugs and I have swapped my coil packs for cylinder 1, 2 and 3 I put them on cylinder 4, 5 and 6 but the misfire still stays on cylinder 1, 2 and 3. any help please will be appreciated. I Don't know if clogged catalytic is causing the misfiring. please help. Thanks in advance.
