2000 Vauxhall Zafira engine management light problem

MY MANAGEMENT LIGHT APPEARED A FEW DAYS AGO AND DID NOT KNOW WHAT IT WAS UNTIL MY CAR STARTED TO LOOSE ACCELERATION AND STARTED TO JUMP ALONG LIKE A KANGAROO!
BUT NOW IT HAS GOT WORSE IT NOW STALLS BECAUSE ITS USING EXECESSIVE FUEL AND GETS FLOODED THREE TIMES IT HAS BROKEN DOWN ON ME AND HAS BEEN VERY EMBARASSING FOR ME HAS I HAVE HAD TO PULL INTO GET FUEL AT OUR LOCAL GARAGE AS THERE WAS A LONG QUE FOR FUEL BECAUSE OF FUEL CRISIS SO I WAS IDLING AND DECIDED TURN IGNITION OFF AND SHE WOULD NOT BUDGE AS SOON AS I PAID FOR MY FUEL GOT BACK TO THE CAR SHE STARTED AGAIN IT WAS ALSO RUNNING AND TICKING OVER ON ABOUT 1 AND HALF ON REV COUNTER.
A NICE MAN CAME TO HELP ME PUSH CAR ON TO FORCOURT AS IT WAS ON AN INCLINE SO HE SAVED ME
NOW THE AA MECHANIC PUT A DIAGNOSTIC TOOL ON IT AND IT CAME UP WITH 2 CODES OF P0135 AND PO130 ONE WAS THROTTLE BODY AND THE OTHER WAS THE OXYGEN SENSOR OTHER KNOWN AS THE LAMBA SENSOR WELL WE CHANGED THE THROTTLE BODY AND ITS STILL THE SAME SO IT JUST LEAVES THE LAMBA LEFT CAN YOU TELL ME IF THIS IS THE LAST ATTEMPT TO SOLVE THE RUNNING PROBLEMS OR IS IT GOING TO BE SOMETHING ELSE AS THIS WILL BE OUR LAST TRY AS THERE WERE NO MORE PROBLEMS SHOWING ON THE SCREEN OTHER THAN THESE COMPONENTS ANY IDEAS GUYS GALS?
