It's very cold where I live. The car has been standin for awhile. Started it up and heard a weird "knock" under the car followed by a screeching metal noise. After the car started right up, but looked like it hesitated with the RPM's at 500 for about 2 seconds before it jumped to about 1500. Just a little worried about the noise. Thanks.
