   Hey
   
   Cars thrown a few problems at me this week.
   
   Anyway. since i have put my induction on my engine management light has been on and it doesnt go off.
   
   Also around the same time a fuse blown for the cd player and the fuse in the back of the cd player had blown. dont know if it has anything to do with it but happened around same time.
   
   Anyone know if ive done something wrong ?
   
   All i done was remove old filter. put new one on attached the arm with a bolt and that is it. have i missed something ?
   
   Cheers

   Did you move/unplug any sensors when you did your induction kit?

   Lambda sensor, the sensor in the manifold
   
   thats your culprit mate
   
   

   Quote:

   Automotive oxygen sensors, colloquially known as O2 sensors, make modern electronic fuel injection and emission control possible. They help determine, in real time, if the air fuel ratio of a combustion engine is rich or lean

   hence your engine management light being on, its not getting readings from its sensor

   either get a blank for it, or reconnect it
   
   not really done anthing wrong mate, also happens when people de-cat their cars, it just means the ECU isnt getting a reading of the emissions going into the exhaust. If you leave it unplugged, as that line says, it helps the engine determine its air:fuel ratio, so your car might run a tad shit

   Hmmm... Only thing i could really think is that it'd need changing, but it was fine prior to removal.
   
   is it seated propperly? (daft question and dont want to be ignorant, but gotta ask these things )

    Hmm, then im not entirely sure mate sorry about that only thing i could really suggest is trying a new sensor all together
    
    it isnt unheard of, that induction kits can cause lambdas to blow so to speak, not sure how accurate that is, but ive heard it alot on here
