Under full throttle my truck hesitates when shifting from 1-2. It bucks too any ideas on what it could be?

Could it be my plugs and coils, could it be misfire?

Possibly you should put a scanner on it that does live data it will show you what's going on. I took mine to a local transmission shop when I was having issues and it turned out to be a miss (this was found out when they hooked the scanner to it which they did for free)

Mileage ?
Maintenance performed ?

150k just checked all fluids and had oil change, I know it misfired 2 times and idles rough, I also have a tuner. But since it idles rough I think I need to change plugs and coils

Have the plugs/COP's been changed before?

Jkob10

I'm not sure bought the truck used I haven't changed them, I've had it for about 10k miles

That would be my first move... a good tune up and replace all the fluids
