HI GUYS HAVE A LOOK AT THIS ONE SEE IF YOU CAN PUT SOME LIGHT ON IT FOR ME.CAR WILL START AND RUN FINE THEN IT WILL START TO RUN ROUGH OR WILL START RUNNING ROUGH AND THEN RUN FINE.YOU GET A P0130 02 SENSOR FAULT AND OR A P0170 FUEL ADAPTION FAULT.WHEN CAR CAME TO ME THERE WAS A UNIVERSIL 02 SENSOR FITTED THAT WAS NOT EVEN PLUGED INTO THE ENGINE LOOM I CONECTED THE 02 SENSOR AND WATHCHED THE LIVE DATA THE 02 SENSOR DIDNT REACT TO AN AIR LEAK OR ADDING OF SOME CARB CLEANER. FITTED NEW 02 SENSOR NOW HAVE 02 SENSOR READINGS BUT STILL RUNS ROUGH.THE ONLY THINGS I CAN SEE ON LIVE DATA IS WHEN THE FAULT HAPPENS THE FUEL FEED BACK RELAY SWITCHES FROM OFF TO ON ???? AND THE MIXTURE ADDAPTION SWITCHES FROM 100% TO 70%. THE CAR IS RUNNING VERY LEAN ACORDING TO THE VOLTAGE OF THE 02 SENSOR.AND THE VERY ODD TIME YOU WILL GET A MISSFIRE COUNT ON CYLINDERS 1 AND 2.CAR HAS GOOD FUEL PRESURE GOOD PLUGS LEEDS ECT ANY THOUGHTS PLEASE ???????
