Yo I got a question! My s type r is throwing a P0121 and some knock sensor codes, reduced performance pops up, what should I replace first?

9 times out of 10 it's probably your knock sensors but to be on the safe side I will check the throttle body and the throttle body plug your throttle body might just need to be cleaned and the plug just might need some electrical cleaner too I will try cleaning the throttle body and see if the codes go away if not then it's probably you're knock sensors
