The check engine light on my 1998 Infiniti I30t was indicating codes that called for a knock sensor and evaporation pressure sensor malfunction (P0325 and P0450). I bought a knock sensor online from Advanced Auto Parts and was quoted outrageous labor costs by a few garages, and the time to replace of 2 hours, as the manifold needed to be removed. When I called Pristine they quoted me a much lower labor rate and told me they could install it in much less time. They fulfilled their promise and I was out of there in less than an hour. Good job, guys. Keep up the positive attitude and honest mechanic work, it doesn't go unnoticed.
