3 times indicates problem with the angle sensor not sure about the 8 flashes though. I replaced my angle sensor a couple weeks ago and got to really try it out this past weekend. No problems at all, nice smooth shifting, so hopefully I've got it fixed for good, or atleast for a while.
If you dont want to dish out the $40 for a new sensor at least try taking it off cleaning it up a little and reinstalling it coating it in di-electric grease to try to keep out the water/mud.
