I have a 2000 Blazer LS, 2 door, 5 speed, 4x4.

Here are my symptoms:
1. "ABS" light and "E-brake" lights are on
2. speedometer and odometer quit working
3. Right after starting the blazer it has no acceleration power, it spits sputters and jumps. I have to hold the gas to the floor in order for her to come out of it, which it eventually does. This doesn't usually happen though if i let it warm up for 30 minutes though.

...the scanner read that there was a speed sensor malfunction. Do all these symptoms sound like they're being caused by the speed sensor? If they are all caused by the speed sensor, which one do I replace the "wheel speed sensor" or a regular "speed sensor" or is there a difference!? Thanks for the help everyone!!

 

Kind of old and I do hope that you found the answer you needed already, but yes, a VSS sensor can cause all of these problems. Recently, another member had very similar symptoms and a simple cleaning of the VSS sensor has seemed to clear them up.
