Long start, & I have to hold the accelerator to the floor in order for it to pick up speed. Rides normal after awhile

The code P1300 simply means that there is no feedback signal from the ignition coil. You need to narrow down what is causing it. The highest possibility is the failing ignition coil in my past experience. Sometimes, other related parts are causing it. I'd analyze the ignition system using an oscilloscope with a high voltage prove and a current sensing adapter.
