I just had my 99 disco II break down. The engine light came on the other day and was going to check into what the codes mean, but it stopped running today. I have codes p1174, p1171, and p1590. I know what the first two are, but 1590 said (rough road signal) Not sure what that means. Any ideas?

 

I have a 99 disco II. It just recently came up with a code p1171. Can that be from a bad fuel pump or pressure regulator? ' Gotta get my wife's baby back on the road.
