In lamest terms 118 means that your computer thinks you need 118% of a "normal" amount of fuel to keep the proper A/F ratio... Meaning you are lean.
 
Thanks for the clear up, but I will not be able to adjust this for a while. My timing belt snap yesterday and bend all the valves. Just a bit no further damage was cause.
Thannks again for the info.
