Engine Problems

I apologize in advance if this is in the wrong section. Yesterday, driving to work, my 2001 Tacoma Prerunner 2.4 L started acting strange. Pulling out at an intersection, it bogged down as if a sudden loss of power. Then it picked up and ran kinda smooth except for a small pulsing at a cruising speed. Each time I had to slow down or stop then accelerate, it would blog down again then suddenly pickup speed. I did make it to my job and at the end of the day, I tried to start it and it rumbled and jerked, but would not start. Pressing the gas, it finally started and there was a large cloud of white smoke from the exhaust. After a few minutes the smoke lightened but was still present. I called a friend and said I think I have a blown head gasket. He asked if there was water in the oil, there was not. He asked if there was Oil in the radiator, there was not. when I put it in gear it instantly died. If I suddenly press the gas, it blogs down. At operating temperature, the antifreeze in the radiator is not moving, but the heater warms fine. I am using an OBD II with the Torque smart phone app and did manage to get a P1130 code. Can someone please help me with what is possibly happening to my truck?
