Ok I searched. I must be using the wrong wording. Any ways my 96 4.0/AW4 with 125,000 miles is having some fluctuating rpm's when I give real light throttle doing about 25-30 mph. At idle its fine and on the highway its really smooth. Although I did notice about a 1-2 mpg loss lately. I guess I need to find my manuals and get my multimeter out. I'm guessing TPS but any ideas or thoughts would be apprecciated.
 
My 96 did this... I replaced the TPS ,took care of problem..

Good Luck

Nick
