Whats going on y'all? so my friend wants to sell me his 2002 wrx sedan and I am gung ho for the buy, but he said that the knock sensor code and is skipping. I have no idea what he means by skipping, but he did replace the knock sensor and it's still throwing the code and not skipping as much. So as much as I want to take the car from him I'm hesitant on paying the price he wants for it. So I was wondering what you experts have to say about this. Please don't be rude guys I am new to Subaru and don't know much and I just want some feedback from the pros. Awesome y'all have a great day.
