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.

 

That sounds more like a vacuum line problem than anything else. The lines from the breathers to the throttle body are your likely culprit. It is common for them to dry rot. You hear a lot less of this from owners with cold air intakes and catch cans since the NeedsWings kits replace the hard rubber lines with flexible rubber hose.

The easy way to check your lines is to spray soapy water over them. Any bubbles will indicate the fault. A visual inspection might even turn up oil near the connections to the breather covers. Try getting some hose and screw clamps from the local parts store, much easier and cheaper than finding the OEM lines again.....unless you're a hardcore purist.
