Check engine

Hello guys, My Lexus RX-300 has a very big problems, i couldn't find the real problem, and also none of the specialist could tell the exact diagnose.
When I'm checking it on computer there are some errors, (P0300, P0171, P90302, P0304) these codes was detected when i checked it 20 minutes ago. Yesterday was (P0125, P0171, P0325, P0330) these codes.

I already change plugs, coil wires, detonation sensor and also some other parts, but there is no result.

Please share me your experience what to do?

Thanks

I had a similar experience including P 1349 and searching led me to the need to replace an oil control value. Without the correct oil the cam will act up and cause misfired on that bank. I just put it in yesterday so I can't say if will solve anything for sure.

When you have multiple codes like this, I've found it best to bite the bullet and get a diagnosis from the Lexus Dealer.

Does the dealer charge for a diagnosis?

Call your service advisor. Usually Lexus charges for diagnosis and repairs. Some time the diagnosis fee can be merged with repair fee.
