For the last couple weeks when I start up and take off cold, my car misses for a few then stops. There's no check engine light on so I don't know what it could be, do you?

I would start with a tune up, new spark plugs and wires, also service the throttle bore and IAC. I have also seen the coil pack go bad, but I would start with the plugs and wires. This guide can help walk you through the service with instructions in the images below for your car:
