I started my car the other day and the rpms kept slightly bouncing downward while coming from 2000 rpms during warm up, and engine felt very shaky like it wanted to stall. It was 27 degrees out and I have 9000 miles on my car. Anyone else experience this? I don't think this is normal.

Just sounds like it was cold and there was a misfire. Did it go away once it was warmed up?

Yeah kind've but the engine was real shaky.

The cold start reving shouldnt happen when its 27 degrees outside. Had it been sitting outside for a prolonged period of time (more than a day or two)?? If not, there may be an issue.
