Whats up,
So after searching around I couldn't find a DIY thread for replacing a knock sensor on a 1UZ-FE. If anyone could explain how to get to it I'd greatly appreciate it, or if there is a thread please post a link. This is making my car undrivable and I need to fix it! Thanks

Here's a few threads I've bookmarked, some more relevant than others:
