2002 Dodge Ram 2500 Question: Why does my truck "lunge" at stop lights?

My truck always "lunges" at a stop light/sign. It feels like someone has bumped me in the rear or the truck just wants to go. The motor does not rev and it only does it for a second but can "wake you up" if your not expecting it. Never had any other vehicle do this.

    That thing is ready to go man! Maybe you did get hit in the a..! Have the rear brakes checked!! Possible contaminated brake shoes,,,,will cause this but only when you let off the brake pedal it will hang then release and feel like it lunges!

    I have replaced all brakes and bled all "old" fluid out for new. I did this because vehicle sat for years in my garage. Fluid was "dirty" and now clear. ABS pump runs so unplugged fuse. Need to get module checked out/repaired. Found a great place that has 24 hour turn around on module for 79 bucks. Have used them with avalanche and worked great and fast.

    Cool. Had a Chevy with leaking axle seal, doing the same thing is the reason for the suggestion.
