A few more info.  The codes I am getting over and over, since the beginning of the year, are P0171 and P0174.

Two of the parts the dealer suggested be replaced are fuel air ratio sensors for banks 1 & 2. According to them, there are updated versions to take care of the 2 error codes.  The other part, mass air flow sensor, they say is not reading up to specs.

Like I said, my mechanic just replaced these parts and he used OEM parts (Denso).

My registration was due in May. I paid the registration but can’t take my car to smog.

Thanks again.

Hi!  I have a 2006 rx400h and I am having this issue now about the oxygen sensor monitor “not ready.” I went to the dealership yesterday and their tech told my service advisor that he cannot find a software update for my car. And I’ve just hung up with Lexus Customer Service and was told she can’t a customer support program for this issue.  The dealer wants to replace 3 parts (for the discounted price of ~$700 and $980 labor) that my mechanic replaced to resolve this issue.

Does anyone know what the official campaign for this issue was called?

Thank you!

I just bought a 1999 GS400 with 110K miles on it and I am new to this forum.

I have read about the steering wheel vibration at speed of about 60mph. So last Thursday night, I replaced both ball joints. And those of you who have done this job know about using cotter pins after the nuts have been tightened.

I read the torque value for the nuts are 119 ft-lbs. The hole for the cotter pins will not necessarily unobstructed after applying the torque value.

My question is: Which is better, to under-torque or over-torque these nuts (for these cotter pins)?

A related question is: Is it okay to replace these nuts with self-locking nuts (which will make the cotter pins irrelevant)?

Thanks in advance.

Btw, my 60mph steering wheel vibration is gone, I think. It's been raining here in NorCal so I have not taken the car out much.
