just to clarify i did get codes read it says knock sensor bank 2 but my car when i accelerate it feels like it has trouble around 20 then boom starts going normal speed. Would the knock sensor cause this? I am going to be getting one and installing it monday. also i did change the throttle body and still same thing happens. ---

> [@Kewizzle](#): > > why not, it was free If it was free, why would you think it was any better than the one you already had? Changing the knock sensor may not fix your problem but that is the most likely reason a P0332 was set. ---
