running problem, O2 sensor, plugs/wires
A quick way to clean them up is to buy a $11 propane torch from Lowes. Take out the O2 sensors and put them in a vice. Hit all 4 sides and the top for 1 minute each. Let cool and replace. I've saved several O2's this way and for $11 it's worth a shot vs. well over $100 for 2 new ones.
