I have a 99 rx300 and the check engine light came on. I went to the lexus dealership and they say that it needs a new bank 1 air flow sensor ratio cost around $400 include labor. They said they clear that air flow issue and the light is still on. They said that the car needs a new exhaust manifold that cost around $315 for the parts and that should solve the check engine light problem. Am I being cheated by the LEXUS dealers or are they telling the truth? How much does an exhaust manifold cost for an RX300?

If it were mine, I'd get a second opinion from another dealer or a good general shop. Cost seems high, but I haven't priced a manifold either. If that doesn't include labor I'd get another bid. The error in diagnosis is also little suspect too.

You might have a crack exhuast manifold. This would cause a lean condition, I would check with another source though. Good luck.
