it feels like kicks
when I start my truck I feel like a little kick when I'm stopped and once you're moving and the truck is gaining RPM and going up in gears, sometimes you feel like a hit or a jump, don't know how to define it, can it be an ignition coil?

Transmission or ignition most likely. I had something like that once on a '90 Escort GT. I had replaced the spark plug wires but not the coil wire. It would 'jump' like that and throw a light. I took it in several times and they always replaced the mass air sensor - then it would do it again. Finally it did it and the engine wouldn't run anymore. They towed it in and it turned out to be the coil wire.
So I'd say there's a good chance you're experiencing something similar, perhaps in the power supply to the banks of COPs.

Buy yourself one of ^^^ those dohickeys, from the Amazon link, set up the Bluetooth to your android phone (doesn't work with iPhones) download and buy a 5 dollar app called Torque Pro, link it up, go to "test Results" drive for 5 miles, with the app running, and park, but don't shut anything off. scroll to the bottom and find engine misfires, keep scrolling down and you will see each cylinder misfire count separately.
At this point, my suggestion would be to replace the spark plugs and coil packs for each cylinder that has misfires, until you get it down to a point when all of them are running almost completely perfect.
If that doesn't solve it, you may have an injector problem. Also, if you can't fix it with a hammer, it must be an electrical problem.
