I'm looking for a decent scanner that will tell me what my sensors are doing. I have a miss/buck action during acceleration that I can't seem to isolate. I've tryed to check everything I can and replace many components, but can't isolate it. If I jumper pins A and B (put into service mode)on the ALDL it runs without a miss. I thought a scanner would tell me exactly what the sensors are doing during accleration.

thanks for the help.
