transmission works fine but once in a while going up a hill I get a little hesitation
The jerking is in the engine itself
rather then take Guesses am going to have to suggest the data from a OBD-II...plugs right into the connector not 20 inches from the ignition switch~ 12 bucks on ebay~
plugged catalytic converter~
intake air sensor this part is ONLY for the 2005 rendezvous~http://www.partstrain.com/store/details/Buick/Rende zvous/Standard/IAT_Sensor/2005/SIAX32.html? source=gglpla&gclid=CjwKEAjwps2_BRC5jduHor-h8xESJADGT- LtWYOPJG07fKFTdIsTNYo-KfVdXXoP7JW-vTIJH- _EAxoCgRXw_wcB
Could just be a dirty air filter too
