2000 7.3 issues please help!

[bigjpxj]

Hey guys I'm new to the form, I have a 2000 f250 7.3, I'm having a issue I think with the injectors? When it shifts into over drive and I'm cruising or give it a little gas the motor stutters and feels like its miss firing, when I punch it at higher rpms it's not bad, I changed the fuel filter but didn't help, also theirs no check engine lights or anything, truck has 235000 miles on it, any ideas?
Thanks!
