Well got the p0332 code today, knock sensor.should I replace both while I got the intake off? Do I need new gaskets for the intake or just rtv it? Anything to look out for? Also I have my right side exhaust is tapping my frame , could the sensor pick this up and it being irregular throw the code? It has done it for a while but now it is doing it all the time, I am about to take it to the exhaust shop and see if they can move away from the frame a little bit.
