ok, ..this might be the timing, not sure....when in drive, brake depressed. my car kinda acts like its wanting to jump forward a lil....itll be like...vrrrRRrrrrrrrr ....best i can explain it, ....and its still making that weird kick drum thud from the tail pipes every 10 seconds...anyone have any clue??

 

Slow,

I have little dount that the "jumping" is related to the "kick-drum" noises. Is your car from the islands? "JA - Mon! We're jammin'!"

I would guess that you need to take a very close look at the ignition system, from the reluctor to the plugs, and everything between. If that doesn't completely cure it, it will at least eliminate a lot of the possibilities.
