Burners… anyone’s idea?

Hello, drive a V8 4.2 on gas., year 2004, ATM has run 190000. I’ve been having the problem for quite some time that it’s jerking and the engine warning light. Yesterday deleted errors and read out again today: Address 01: Motorelectronics Label file: 4D0-907-560-BGH.lbl Part number SW: 4D0 907 560 CQ HW: 8E0 907 560 Component: 4.2L V8/5V G 0040 Coding: 0011873 Operating no.: WSC 68578 512 00000 VCID: 77B0D4F348873FBDA9-5178 3 Error codes found: 16684 – Burner detected P0300 – 001 – – Warning light EIN 16692 – Cylinder 8 P0308 – 001 – Incinerators detected – Warning light EIN 16690 – Cylinder 6 P0306 – 001 – Incinerators detected Readiness: 0000 1101 Renewed the left LMM in driving direction 4 weeks ago. But somehow the incinerators come back. Oddly enough since the latest the phenomenon that he stops flashing as soon as he jumps on gas and runs a lot quieter…. may sound strange, but I am also the opinion that if there is more gas in the tank, it causes less problems. Ne real Diva just…. :/ Does anyone have an idea? Thanks for your help
