Does flooring the throttly while starting change the car's behaviour? Let your car sit for a night or two and then pull out the plugs. Look at them and the cylinders. If they're wet, you probably have leaking injectors. How does the car run at higher RPMs under load? Ignition problems mostly show up under such conditions. Another possibility might be the ECU, but at the moment I doubt that.
