Hi Hi, was wondering if you ever got that prob solved? i think i might have same prob, mines real bad acceleration or up hill under a load. mines 2002 se 3.1 with 109k on it, i changed a bunch of stuff on mine so far, but no luck. someone recommended changin ICM ( ignition contrl mod.) thought that was gonna help mine but no such luck, still scratchin my head. hope you have better luck than me.
