e4od problems!!!

my 89 f350 460 efi e40d has got an issue, first when i press the gas pedal it accelerates just fine but when i go to press the gas down hard it seems like it doenst accelerate as fast as i did at partial throttle. and second, when it shifts into over drive and i go to speed up a bit it starts bucking until i press the gas down far enough to wear it shifts out of o/d. now i took the battery cables off to reset the computer and put them back on and drove around and it was like brand new then it came back to bucking again. could this be the computer problem or something else. thanks for all the help.

I would check the throttle position sensor. It sounds like its choking.

thanks guys, i replaced the iac, and the sparks plugs, wires, cap and rotor and that fixed it. no bucking and no throttle issues, i dunno but thanks for the advice.
