Im having a problem here and i'd appreciate any advice on this issue. When I started my car in the morning everything was fine but then later in the day I started the car and the rpms went up to about 1000 and then jumped down to 0 and stalled out. Then I would wait a couple seconds and try to start the car again and it would work completely normally. This happened 3 seperate times today when I tried to start the car. Also, for the past week i've been noticing a really weird noise coming from the rear of the car. I cant tell exactly where its coming from but its coming from near the rear wheels, and I dont think its the brakes because i just got new ones about 1 month ago. Thanks in advance for any help.
