The heater circuit might be a fuse. It is a relatively high amperage fuse, it is PROBABLY marked "HEGO" . I would check where the O sensors are connected, see if a wire is pulled.

I'm pretty sure the upstream and downstream are the exact same sensor, perhaps with different length connectors. Borrow one of your downstreams and switch them out.

If you can get them out.

The thing is... none of those would cause it to run like it does. You're missing something very simple I bet like a one wire thing.

A MAP sensor would do that too... I don't think they started map sensors till 2001.

I'm kinda lost without 2 full manuals.
