Today, I recently noticed my check engine light turned on. I went to check it out, and it gave me two codes:PO 400, PO 325. I know one is a knock sensor and the other I believe is an EGR Position sensor. Can this affect the car? and how hard is it to replace? and if anyone here has the parts here im willing to pay.:wackit:
