   Hi all I need some help please
   
   I have had my sax since July 2010.
   
   Basically I have been getting around 60 - 70 miles to a tenner.
   
   All of a sudden over the last few days this has dramatically dropped to around 25 miles.
   
   If it helps the car has
   
   Induction kit
   De-Cat straight through exhaust
   No lamda sensor connected
   
   Any help or advise is greatly appreciated.
   
   Tom

   That is driving economically haven't changed my driving style at all.

   As far as I'm aware the lambda sensor is used to measure the amount of oxygen in the exhaust pipe, therefore it can detect if the car is running rich and adjust the fuel input accordingly
   
   This gives abit more info

   Thank you for all your feedback.
   
   The problem is that when I brought the car the lamda sensor was already disconnected. So can that really be the answer to the poor fuel consumption ??

   Plug the lambda sensor back in. As said before it's a measurement sensor for the car to Adjust it's fueling as required. It's like taking away the cars sense of smell.

    You partly answered your question in your 1st post mate all the things you`ve listed won`t help your fuel consumption 1 bit.
