Yesterday I went and started my car, let it warm up for a minute, and as soon as I was ready to leave it died... but started right up. This morning, I started it, same thing happened... only this time it wouldn't start right up.. after waiting a few minutes and trying again, it came right on like nothing.. no lagging at all... What could this be??? I have an 03 GT, not even 1k miles on it yet! I'm beginning to think I need to give up mustangs.
