It's normal. My car has done it ever since I got it, and I'm sure a lot of other people will chime in here soon enough with the same sentiment.

You might want to think about changing the plugs anyway with 53k on them. It's not necessary, but you're probably leaving a couple of hp on the table.

It drives me crazy, I have it on GT as well. I do not know what causes it...The only thing comes to mind is not the proper amount of fuel is being used to turn over, or maybe the injectors need a cleaning..who knows...

When you turn the key to the run position you should hear the fuel pump run for a few seconds then shut off. Try cycling the key so that the fuel pump primes 2 or 3 times before you start it. See if that makes any difference.
