Hello all First post on the forum nice to meet you
So I bought an astra 3 months ago and realised it had an EML. I checked and the EML was for bank 1 lambda sensor so I got it changed and still got the same fault codes. I then took it to a mechanic and he changed the timing chain, the water pump and the oil. I was having a rough idle at the time and this helped a little bit with that but it didn't sort the sensor light. I then got a code showing for a mis fire so I took it back to the mechanic and they said the coil pack was done and that I needed a new one. so I got that done aswell. Again it improved the idle however I still kept getting this bank 1 sensor fault code and EML. What could be causing this if its not the actual sensor?
