New coil pack installed less than (3) months ago. Starting the vehicle... idles perfect. Back out of garage and down the driveway to the street. Put car in first gear and start to drive. At about 2k rpm car starts to hesitate. Step on the gas to get it up to 3.5k rpm to shift. Won't go that high. Really step on the gas and the tach drops to 1k rpm meanwhile I feel like I'm driving Jed Clamparts truck from the Beverly Hillbillies. Stop the car and shift into neutral... again car idles perfectly. Wait and listen to the radio for about (2) minutes. Step on the gas and the car revs like normal and I drive away. Only misfire codes on cyl 1&2 no other codes. This happens the exact same way everyday.
Some kind of sensor or something is telling the ECU that the engine somehow has significant problems on startup????

Any ideas on a sensor? Since, plugs,wires,coil pack are new.
