On the same note yesterday i drove through carwash and as i was going through the dryer the service engine light started flashing.check it and code P0300 misfire on the drive home went away, today P1133 came back.
Thanks in advance.

The cause for this code is not enough O2 output switching. bad wiring / connectors at the PCM /exhaust leaks / etc.
with the car wash incident your wiring could be messed up.
also check fuses especially the O2 heater fuses/sockets for security.
people wiggle the fuses for removal. this damages the socket.
remove the under hood fuse box from fender, check those wires and connectors under there for damage [rodents]
