2000 Mustang GT has the following codes:
P1000 Check of all OBDII Systems Not Complete
P1451 Evap. Emission Control Sys. Vent Control Valve Circuit Malf.
P0135 Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
P0141 Heated O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 2)
P0443 Evap Emission Control System Purge Control Circuit Malf.
P0155 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 1)
P0161 Heated O2 Sensor Heater Circuit Malfunction (Bank 2, Sensor 2)
P1409 EGR Control Circuit Malfunction
I did track down a blown 20 amp fuse under the dash and an O2 sensor that a wire was frayed. Replaced both and SES light came back on 30 mins later.
The only driveability issue I have is on cold start to warm up, the SES light turns on and car idle will surge and die.
Once up to operating temp, vehicle does not display any drivability issues. I can clear the codes out and drive just fine, the SES stays off. A few second after restarting the car, the codes will throw again.
New engine about 500 miles with 0 issues. This problem presented shortly after switching from Bassani catted X-pipe to a BBK not-catted H-Pipe and hitting a speed bump. The H-pipe was supposed to be handled via a Bama tune, they verified they adjusted the tune correctly.

check the harness from the o2 sensors up into the engine bay. you may have more wire breaks further up the line.

Egr is most likely the dpfe there was a recall on it ten years ago.
An the only way to really diagnose the o2 problem you going to need a scan tool with mode 6 or know someone with ids so the can monitor the pids.

You have a heater circuit issue. Because it is on all four O2 sensors would lead me to believe you have a short in the heater circuit that blew that fuse. Check to see if any wires are hitting the headers or exhaust and repair accordingly. The other codes should be also easy as you just installed an exhaust and overlooked something. The other codes most likely are fed by the blown fuse also. To have all those codes most likely a battery is missing from those sensors.

Thanks for the input. Got it to a friends shop and up on a lift. Simple fix was the fuse blew again after noticing another O2 sensor wires were touching the exhaust.
Fixed everything and had the rear 02's turned off. Good to go now.
