scanmaster problem

[DAVE69]

It's been awhile as the car is put away for the winter,but from what I can remember my scan master was acting up . What was happening was that when at idle or just cruising it seemed to be alright,but when I floored it, the scanmaster would go blank.The only way to get any reading back was to shut off the car and start over.I know this isn't much info to go on but I thought I would ask the question to see what info I would get.Any help would be apprieciated.thanks DAVE

Make sure ya got the signal wire connected into the correct ALDL slot. It will act funny if its not in the right slot.
