   Not sure if the two are related but i'm getting the error code:
   
   02 circuit sensor bank 1 sensor 1
   
   I'm also getting flat spots while driving. Mainly at around 1500 rpm but also a few at higher revs and more so while the engine is cold.
   
   I've changed the lambda sensor and still nothing. Anyone know wot it cud be? Cheers

   That's error code P0130 which I know means the pre cat green plug lambda. But i've replaced it with a new one .

   Yh it was a cheaper make not an NGK one. Got it from eurocarparts. Cud b the reason but I also tried a used one that I bought from here and that wasn't working either. So i'm thinking it's something else.

   Try unplugging the battery for a while,I know it`s a long shot but i`m out of ideas otherwise.

    I tried unplugging the battery for a while and it didn't do anything .
    
    My engine management light isn't on atm it turned off when I put the new lambda in but the problems didn't go away.
    
    Cud a blow in the exhaust possibly cause this? Because putting my new backbox on got rid of the light that night. But I had changed the lambda for the first used one I tried a few days before so I assumed it was that. The new backbox fitted better than the last. At the time I thought it cudn't be .
