Trying to get my 96 Maxima inspected-

I went to get it inspected-they told me the tint was too dark and the tail lenses were broken. I had all that fixed. Then took it back and now they are saying the knock sensor (p0325) and insufficent coolant temp for closed loop control (p0125).:banghead::banghead:

I am in school, I have to have my good ol' Maxima to get back and forth and can't afford to miss any.

I have the knock sensor on order, I need to know where I can get it installed and how much this is all going to cost. Anyone have any advice?
