Im wondering if the 02 wires could have been damaged from getting pushed down with the 02 tool. Or if any ECU or whatever wires could have gotten pinched or such from moving the ecu out of the way during downpipe uninstall
hmm. I would check all of your ecu connections then. Both banks obviously. The most defined way to do it would be disconnect and reconnect each of them. You could have 1 connector not fully seated. Look for that first.
