Elpachio

I had a service yesterday and got them to check why I get an intermittent engine warning light at high revs in damp conditions, and some occassional "hopping" when cold as if there's a fuel blockage.
They referred to code 43......fuel supply, but he specifically referred to the lambda circuit.
Considering I only had the lambda replaced just 17000 miles ago when I had the catalytic converter replaced, I am dubious as to whether this is the actual cause. Could code 43 mean anything else in a 95 Lude?
I also had the egr valve replaced last year.

Also, does anyone know how expensive it is to replace both rear anti roll links and bush kits, which are worn?

Thanks,
