I wouldn't use Roys, this week they couldn't even replace an oxygen sensor for me, due to fear of handling the hybrid systems in these cars. They'll do your service and wheels (the easy money) and leave the real work for a proper mechanic...

Gah, this replacement sensor is driving me nuts! I've been trying to replace sensor 1 bank 1, but just cannot get any leverage on the sensor in the position it's mounted. I have used my smallest socket wrench with a specific sensor socket (http://www.amazon.co.uk/Lisle-12390-Oxygen-Sensor-Wrench/dp/B001C6NE40), even putting a small wrench extension in, but just can't get any position which lets me apply force. Anyone got any tips for this removal?

Sooo, I'm a newish 2007 GS450h Lexus owner, and have got a few error codes appearing on her :( They are as follows: Am I right in saying, these are all just a dodgy bank 1 sensor 1 (engine bay) and possible sensor 2? Is replacing them myself feasible? I'm from the UK so would want to import Denso sensors from the US (OE parts but way cheaper?)? I have to figure out the part numbers first, unless anyone here knows what they are? It seems like a lot fewer people have embarked on this job with the GS450h than they have other models, so any advice would be amazing!
