Greetings folks!

year long member, but this is my first "productive" post (if you can call it that)

Much apologies from the start because i'm sure this is a dead horse for a lot of you. I am going to be replacing my knock sensors in the next couple weeks. I have been searching & searching all over this forum and cannot seem to come up with a DIY for it. I know the general line of attack, but was hoping to find a dumbified step-by-step for the 1uz... I am going to turn this into a pretty good tune-up time but was wondering....

what other parts HAVE to be replaced during this repair?

is it just the intake manifold gaskets, sensors, & sensor pig-tails(harness)?

what are the "its a good idea" parts to be replaced? ( i saw someone mention the starter, but i dont have a starter issue)

any special tools? pullers or crazy-angled wrenches, etc

THANKS for all those that took the time to read this babble! By all means... call me newbie and cyber-backhand me, just as long as it comes with a link!
