I have a 97 disco 4.0 v8i. I cleared a p1193 code with the OBDII reader. When I rechecked the OBDII there were four flashing monitors and several that were solid. After driving the Rover two of the four flashing monitors became solid. I still have two that are flashing. Does this mean that the two, which are O2 monitor and the evap monitor, are still testing or do they just continuosly test and will always flash like that.
