so I went to take off earlier today. truck was full warmed up and had already drove around town a bit and everything. got into third gear and just completely lost power, no light thrown or anything. let off the gas, tried to get back into it and same thing. had to pull over, came to a complete stop and the whole truck just started jumping like a misfire but just had plugs and everything changed about 10000 miles ago. 2012 eco super crew xlt, 162000 miles. it is the 6 speed auto and has had the reprogramming that sometimes feels to be worse than the original program I started with.
