I have porsche 2012 3.6L 220kw and I get P1583, P0301, P0302, P0300 (with cheap ELM bluetooth)
Issue is with max RPMs it throws CEL, PSM and "start/stop deactivated" errors. And it starts misfiring and vibrating crazy.
But the weird part is that it still accepts gas and its possible to rev the engine. And after switching ignition off and starting it again - only CEL light remains there but no misfiring and no hesitation until full throttle.

What I already tried:
1. Swapped coils and plugs - nothing.
2. Changed all injectors (to new ones). Event the rail and high pressure sensor - nothing
3. Changed all coils and plugs - nothing
4. Changed oil mist seperator - nothing
5. Checked if there is vacuum leak sound - nope. (had such issue, the whistling was pretty high and RPMs were fluctuating massively)


Can this be caused by intake manifold if it's sealings are not new? There were plenty of work done with this car and it was removed quite many times.
Thanks for any insights!

 

So the issue was clogged catalytic converter. Removing it solved the issue
