Hello all,

 I have a 2000 Nissan Frontier, 5speed V6 4x4.  About a year ago I had a "full" tune up:  new plugs, wires, cap.  I had this done due to rough running, jumping motor while accelerating, and it worked.  Now I'm experiencing a "bump"/"jump" while I'm cruising at highway speeds, with light to moderate acceleration on the motor (going up a hill.)  The check engine light isn't coming on during this event.  Could this be caused by "bad" gas, or is something wrong with the ignition system.  Should I change any other components of the ignition system.  The problem seems to be more active when the motor is warm.    Currently the ABS light is on, but I assume that doesn't have anyting to do with what's going on now? (Maybe)......

The ABS light was on WAY before this issue.

...thanks for your time.
