Pre cat??? Hmm not reall emmisions trhen if its Pre cat

 

[drhowser]

is it possible the lambda has been damaged or is not clipped in correctly?

 

[ad1uk_08]

not to sure will check tomorow has no one had this problem before with a decat?

 

[drhowser]

it's normal for the post cat lambda to trigger the emissions light, but as coby is saying, it shouldn't affect the pre cat one.
