Hi JimB....
are you shure is a fault code????
may be your ev-100 control card is bad and your dysplay show 88 because dont have the massage from the card.....
remember for a fault code the display have to show "-XX" the minus sing is important, if you dont have is not a fault code.
i hope it helps.....
