ok found the problem i think. upon looking at the maf sensor i did notice that theer was a crack where i guess a seam was on the top of the sensor. i stuck my finger nail in it and the whole top half of the sensor came off and the gooey stuff inside was there. i closed it back and started engine. upon opening it up a little, i noticed the engine act like it was going to die and upon opening it up all the way the engine did die out. so i just unplugged it and started it up and drove it round a bit until i get the new maf in the mail. so far its not as bad bucking in acceleration. i went ahead and did order an new maf, throttle position sensor, and a new idle air control valve. also going to change the plug wires while im under there. hope this works. havent changed any of the sensors i bought yet so its prolly time. car has 111000 miles on it. hope the hesitation and bucking stops. ill keep u guys updated.
