Ground buss.. yes.. Pat..it'* possible (but you need to say where it is..
There is one under the front carpet on each side of the car. This is a rectangular item that is taped to the wiring harness. Water issues under the carpet will corrode the ground and cause isses.
On the misfire..double check that no plug wires are touching the wires for the O2 sensor. That will cause a mislike feeling.
I do feel that this sounds much like a PCM though. Await Jr's3800 to see this, he'* like the resident expert on bad pcms and knows the usual symptoms.
Climate control has sensed a fault in the system somewhere. Try searching on calibrating it etc. Echo SSEi is one of the experts with that system.
Hang in.. you'll get it going right soon.
