| Re: O2 Sensor bank 2 cts Tail light stay on Wecome to the forum. It was common to feel the shake in the 03 engine. I have the same problem and have sat in a few more and they all seem to do it. You should replace the bad O2 sensor, but I don't think it will fix the shaking. I think there is a mod for it where it raises the idle RPMs to 800 but I'd rather have the lower rpm and live with the shaking. I don't know if the new O2 will change the fuel economy, but you won't be able to pass an emision test with that problem. Good luck |
