i have a problem with my 4.6 v8 range rover it seems to run rich on fuel. i had 2 fault codes come up they are p1138 and p1158. i have a basic dinosotics kit for myself so i had a litle look and the only thing i can see is fuel system 1 open and shuts when driving normally but after a while it comes up with fuel system 1 open loop due to system fault. does any one have any ideas on what is wrong and what i can do.
thanks
