I have a similar 'hesitation' problem with my '96 but at parking lot speeds only and not all the time. I suspect the throttle position sensor and am trying to ignore the problem until it gets worse. I'd like to open up the TPS, clean it, and have the problem go away but don't know if that is possible. The TPS looks to be just a big (expensive!) potentiometer.
