Just recently purchased a used 99 RX300 and I am getting P0330 error code and today I noticed that it wasn't shifting into cruising gear it shifts 1-2, 2-3 but didn't notice 4th gear and tachometer is at3800-4000 @60 mph. It also doesn't down shift to pass. So the ? Is does the knock sensor and the shifting issue correlate with each other?

Please read through the sticky threads. Also use search.

We have at least 2 DIY's that go over the knock sensors.
