The OBD II code for P0400 is Exhaust Gas Recirculation Flow Malfunction.
I'm sure the only thing you have left is you may have to replace the EGR valve or check for any leak from the vaccum lines going to to EGR valve.

A code P0135 may mean that one or more of the following has happened:
= O2 Heater element resistance is high
= Internal short or open in the heater element = O2 heater circuit wiring high resistance = open or short to ground in the wire harness.
What to do; = Repair short or open or high resistance in wiring harness or harness connectors.
= Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)
A code P0141 may mean that one or more of the following has happened:
Same as above: mentioned in P0135.
What do do is the same as above, so i am leaning towards and faulty wire harness since you have replaced both O2 sensors. Make sure the wire harness has no break in it or crushed connection clips. The other thing to look for is a bad fuse that is used to heat up the O2 sensor. It may not say O2 sensor on it, it may piggy back off something else so check all the fuse and make sure the O2 has a good ground and not corroded. Good luck and hope this helps.

CHECK FOR FUEL AND SPARK FIRST.
CHECK ALL THE CONNECTORS ON EVERYTHING, ESPECIALLY THE IGNITION MODULE CONNECTIONS. THE CRANK SENSOR OFF THE BACK OF THE ENGINE COMES UP ALONG THE FUEL LINES AND CONNECTS TO THE IGNITION MODULE.

the egr value tubing also gets corroded with carbon. take tube off and use a wire brush to clean tubing. i talked with a mechanic and he said he has never seen an egr valve fail. most if not all egr problems are due to carbon build up in the egr tube. clean egr tube interior.
