Well, rehash, the P0420 comes and goes, around town driving it comes on, If I take a highway run that's 2 tanks of gas or greater it goes off, though at some part throttle conditions it seems a little rough, have to investigate any vac leaks, time for the garden hose. It may be time to hit the boneyard, grab a chunk of an O2 sensor harness and put the resistor/cap in that versus chopping up a good sensor. Figure that'll give me matching male/female plugs and some wire leads.
