It's cool, English is not my first language either. In any case, the simplest way to solve your issue would be to take it to the dealer. As I stated earlier it is a power train issue (including but not limited to engine and transmission). Go to the dealer and state that you suspect a possible carbon build up. Don't say anything like "I tried to fix it on my own" because it could possibly ruin your chances of getting a free repair because dealers want to make money too. They should then inspect the car and provide you with a loaner/rent car for however long your car is stuck in the dealer. They WON'T charge you or at least they are NOT allowed to charge you without your consent to repairs but theres a high chance that the repair is gonna be free. (In fact it is most probably going to be free but you must be ready for the worst case scenario).

If you feel like you're being ripped off, call local repair shops and see how much they charge for repairing whatever issue your car is diagnosed with. Make sure the quality of repairs is high as well (although I personally would rather stay with Lexus but I'm not sure how the quality of labor is out there in UK).

Also is oil consumption
When i look under the car on exhaust just behind the lambda sensors is like two bigger size of exhaust pipe! When im knock in one sounds as the empty glas of wine! Second sounds as full glass of wine! Can this be block and create this issue???? Im live in UK and not sure my problem will be sort out for free!! ???
Delays in acceleration on high speed ( tranny seems to think what shuld do and what gear chose)
Driving on 2nd gear and half way press accel.pedal won't go thru on 2nd gear ( shift up to 3th)
Again so sorry for my language is so dificul to explain all this things!! Im so like my is and 100% next car will be IS too!! Whatt is aprox cost of repair ( carbon build up issue ???)
Many thanks!!
