When I had a problem with all camshafts, the master put me in the wrong way from the Toyota Sienna, which looked the same, but it was wrong, I miss fire  error, I drove some 4000 km until I got the original part. And since then I have a problem of losing power. I do not know if that could have ruined anything? !

I changed oil almost a couple of days ago, it's not even up to that. The Battery is new.

That's exactly what's happening, I love the car very much, and I do not want to sell it.

Yes I know.
The only error that comes is P0420.

Greeting.
I've replaced both of the catalysts, and again I have the same power loss. . I do not know what next I do?

Thank you. I'll report as soon as I change it with the results if I have solved the problem or not.
Thanks again.

I never changed, the car was with me for 5 years, I transmitted it with 120,000 km, and I never changed it.

Regards to all.
After 6 months, it just got me out of this mistake. I hope this is the problem that I have. Does any of you know, is this a mistake that made me trouble?
Thank you all.

I had a problem with the vvti camshaft, one of the three clocks holding the camshaft turned off during the drive and set me up for the fault for the camshaft sensor. I opened both covers to see what the problem was, and all the cables that I myself had broken out so that I could open all that. I could not replace myself, so I drove him on the trailer, but in order to climb the trailer I had to give a contact so I could control the steering wheel, I gave the contact for a few seconds, and then at that moment most of the cables were broken. I drove the car to the craftsman replaced it, and since then I have this trail. Is it possible that some of the hybrid controller computers lost some memory, or did something break up?

And I thought it was, I also replaced the pump oil with a gearbox. Again the same problem.

I was on the Lexus service, they made a software update, and they told me everything was ok with a hybrid, and that they do not know what the problem is, as if it would take more hours and days to detect a breakdown, It's worth it because the car is old and it has 280,000 km.
They even told me that I do not need to do a Hybrid Health Check’ to throw money as a fool.

All cleaned, all done properly.

I replaced the hybrid Battery. And this 12 volt is in good condition.
It's a little bit less English going on, I hope you understand? !
I think there is some problem when it gets hot, but I do not know what it is because it does not throw out any error.

Posting.
I am from Europe, more precisely from Austria.
I have a problem with Lexus, which for six months can not be solved by anyone, so let me try it here, I hope someone will help me.
I'm driving Lexus GS450H 2007.
It happens that after 20-30 km of slow driving, the car starts to lose power at the moment when I give it a gas.
at that moment, it starts to empty my hybrid Battery, and it will not fill it until I reduce the speed to some 80 km.
Then I drive it some 15-20 km at a speed of 80-90 kmh and he is supposed to cool and then everything works again as it should. Again, when I raise the speed of more than 140 km, it starts again after a few kilometers, to lose power.
I replaced the Battery because I thought it was up to her, and with the new Battery the same happens. Maybe someone knows what the problem is.
It does not make any mistakes on my computer.

Every help would come to me well.
Thanks in advance
