Ok so after digging my car out of a mountain of snow, my car started pretty easily even though my idle sucks. I drove around for about an hour, parked my car and went to sleep. I tried to start it this morning and it just cranks.....uhh what should i do? lol. The only code i get is 52 and ive been getting it for the past week i need to rewire my knock sensors. What should i do from here? Thanks for any input
