2007 F150 Harley Davidson loss of engine power
 

2007 F150 Harley Davidson loss of engine power and severe off balance feeling in the engine. Driving along everything was normal, stopped at a light, and when I took off I had 1/2 the power. When I tried to accelerate the entire truck shook and felt like something was out of balance real bad. About two blocks later the check engine light came on. The truck has a self test feature and went through the tests with everything saying it was okay. When I say it had an out of balance feeling I mean everything in the center console and the glove box was sloshing around and rattling. Usually you never hear anything in this truck. It's a very smooth ride all of the time. But I made it home and something is terrrrribly wrong. Can someone help?
