throttle hesitation

[xironworker2003]

98 4.0 when I give it throttle it hesitates to much. I replaced the tps no change.i sprayed carb cleaner on t-body no leak. do you think I need a new t-body? what about a junk yard t-body.what should I look for?

Check your throttle cable, they stretch. Link here as to what to do to check/fix it. http://www.therangerstation.com/Magazine/Summer06/throttlecablemod.htm. Other potential problem areas are the throttle position sensor and the IAC ( Intake air control ) if this does not help.
