ok, i drove to my mum n dads tonight, then got on a straight bit of road and floored it, then pop, oh shit, something was blowing really badly, i thought it was the turbo, but it wasnt because it pulled just like before, then i thought bout the manifold cracking, but it wasnt because ud loose power. anyway got home and found it was just the exhaust temp sensor that goes on the bottom of the de-cat had come loose and come out. all i need to know is weather i need that sensor, or could i just blank it off?? cheers
