Just bought a used 2007 F150 5.4 with 90000 miles on it one week ago. A few days ago i put it in reverse backed up fine and put it into drive and when i hit the gas it had a feeling like i was driving on a washboard until i let off the gas. It did this for about 1/2 mile then quit. drove the rest of the day with no issues. Then i drove it the next two days with out an issue. Now today it acted up again. NO CHECK ENGINE light came on and it always goes away. Just seems to do it right after i start driving it at the start of the day.

Any ideas?

My 08 4.2 did this, it was a combo of a leaky injector and bad coil pack
