I have a stock 91 coupe, L98 automatic, in the center of the guage cluster next to the digital speedometer is a display for the mileage range. The problem I am having is that the display will alternate between the mileage range and SYS will flash, this will continue the whole time the vehicle is in use. I never herd of this before and cant find anyone who has seen this. Anyone know what this is? any help would be great Thanks
