   As mentioned several times in that post, its likely your CAT
   
   Could also be the O2 sensor

   dont sound like blowing and got someone to check this afternoon they said the hc emissions max can be are 200 mine are 104 and lambda sensor max 1.030 mine was 1.025 they passed but just co it fail on at high revs only on natural idle test pass easy but just on fast he said could be something simple in air flow or something like that
