My car feels like its mis-firing, Every once in a while it will sputter and jerk like its miss firing, but the weird thing is, is that it only does it when I go over bumps.  I changed out my plugs and it has drastically decreased but it still happens.  Im thinking I might have a bad wheel sensor or maybe a bad coil pack but other than that I am at a lost.

Any input would be greatly appreciated.  

keep working on the ignition. Check the primary feed to your Alternator. To me, it sounds like your loosing spark because your intermittently loosing power to Alternator. i.e. Hall switch or what ever type you have. Also, check for a loose *** in the alternator, loose connections inside and out. Clean all your Modular connections on the ignition. Sometimes just unplugging and reconnecting them improves a condition. Just for S's&G's swap out the coil wire. Geezz, I know what your going through brother...hang in there  

Thanks man. It freaking frustrating,  My car utilizes coilover packs.  So it could also be 1 of 4 coils.  Im gonna swap them out with a freinds car to see they are the problem since thats super easy to do.  If I dont succeed with that then I will start looking at the alternator.  

I dont know if I found the problem or not, since the problem has always been intermitent, but it hasent acted up for 2 days.
I was lookning at all my grounding points and noticed that the area around my engine wireing harness grounding point was dirty and greasy. So I disconnected it and sure enough there was a sit load of grease and dirt on my contact points, so I just cleaned them up and its been good so far. I'll keep you guys updated.

Thanks for the help.  

check your timing... it could also be a fuel pump how"s the fuel filter?  

I was thinking about replacing my fuel pump just for good measure,(i figure its gonna go soon anyways) but when I do datalogs (I can hook up my ecu to a laptop) and my car starts hesitating, my a/f ratio is still very good, it doesnt lean out at all.

My timing is good.  My filter is an intank, self cleaning filter, they dont get changed.  

Thanks for the input.  

problem was good for a week but its starting to act up again.
