Hi,
changed the crank position sensor and nothing changed.
I changed the o2 Sensors and car seemed to run fine for couple of hours, but error returned!
At changing the o2 sensors i noticed that both sides had different temperatures. one was colder.

update!
Car is checked at Lexus for 2 weeks now.
They first thought there was a vacuum leak at the intake plenum, but the problem still exists.
They found out that one half og the block is runnung 200 degree celsius colder than the other.
There is not much left! they also tried to order the engine ecu to try that out! But the ECU is not for order!
They need to build it!!
I hope they will find the error with the help from Lexus Germany!

I would ask why there is a temperature difference in the block and question the cause of this. Then ask whys at least 5 times to get down to the root cause because they sound like they are just guessing!!
