2008 f-150
i could use a little help. i have a 2008 f-150 5.4 liter. i am having a problem with the engine shaking. it usually happens when im trying to accelerate. obd 2 reader says i have a cylinder 7 misfire and a wheel speed sensor problem. i have already changed all the spark plugs without braking any woo hoo and changed that coil pack. it also will not start on the first try after its sat for a while and cranks right up on the second try. any help would be appreciated.

Sorry it took so long to reply and thanks for the tip. All the sensors looked good and after replacing the spark plugs and a coil pack I decided to take it to the dealership. Naturally they replaed the coil pack and spark plug on a cylinder that was kicking a code. I had already replaced it. Next they swapped the injectors around. This did'nt help either, they say I have low compression on the number 7 cylinder. so now im waiting on approval for them to replace the motor. Thank God for that power train warranty.
