Hello guys, I have an issue with a Peugeot RCZ 2011 1.6 THP200.

Long story short, car went into limp mode upon hard acceleration, started to missfire.
Next day cleared codes and I did cold start, car seems to work smoothly (no missfires, no rough idle)
When it works for abit (aprox. 30-40sec.), car slowly starting to missfire and almost chocking. But it doesnt shut down. When I rev it until 2,5k-3k rpms, check engine light comes up and rough idle.

I have diagnosed the car and I get error codes such as: P1338, P1336, P1030, P1062
(picture attached)

Spark plugs were changed.
Injection coils and VVT solenoid sensors checked and working!
Turbo pipe has been replaced due to cracks.
No rattle on cold start, timing belt sounds okay.

If you had simillar issue, could you please advice on what should I check next?
Abit frustrated, but I believe it can run again smoothly.

Thank you for your time in advance! 😁
