I finally exchanged my ignition coil with another working 300e and i couldnt test the cold start but it still had rough idle and flat spots throughout the whole accelration band. Im suspecting fuel now forsure, EHA possibly?? On first start up dead cold the car, once started runs awesome, no idle problems, no sputtering, accels perfectly but as soon as i shut the car off and come back and drive it minutes or hours later, all the problems come back
