I would get new spark plugs, at least take the distributor cap off and check/clean it, get a tank of premium gas, and head north. Take the 5 north, ignore the sign that says turn the AC off (but keep an eye on your temp gauge) and turn around at Templin Highway, that will take you up the steepest part of the grapevine. And when you test it get the cat good and hot, idling isn't hot enough.
