LTFT -100.

[ray selley]

morning all

my 2011 1.2 clio missfires slightly when cold also has a little engine knocking only when cold.
my LTFT is -100 constantly.
my b1 s2 post cat has a voltage of 0.080 to 0.125. even when warm.
I've changed coil pack, leads, plugs and pre cat 02 sensor.
any ideas
Thanks Ray

I forgot to had also had the check injection light come on. but went off again. there is no fault codes other than" oil level sensor"
