Well I thought I had this solved today. I went into the engine
compartment and traced the three wires (there are three right?) that
come out of the o2 wire that leads from the cat. All of them were
disconnected.
Two of the wires, both white, were disconnected at the plug. Theplug
was very difficult to reconnect. I actually had to put a tie wrap on
it to get it to stay together. I recognize that there could be a
problem with the connection here. The other wire, the green, was also
disconnected.
I put the lot of them together but I'm still getting the bucking. Any
thoughts? Could the fact that these were all disconnected have gummed
something else up?
