In the morning when it's cool outside I will start my car up with no issues but as of late when it starts it reves up real high then settles down after a few seconds. This is happening more often. Yesterday I started it and it was about 80 degrees outside and it cranked over and it seemed like it caught at the last turn.

I love my car and it is super reliable but getting worried. Could it be my battery? I'm thinking some low voltages could be triggering this stuff.

When it reves up at start it concerns me because it sounds like it is way to high for a cold motor. Other then that it drives fine. I do notice that the electric fan comes on a lot.
