...well, first I'd take the black battery cable where it attaches to the frame/ground....take that bolt off and wirebrush the mating surfaces....lug and chassis both...bolt them together for renewed ground potential...then I'd get a NEW battery if yours is older than five because these tin/antimony batteries stop accepting a charge slowly, ten percent per year...get a NEW one~ with refreshed ground things should start to behave normally~

Although the battery may be in need of replacement, there's much more going on than that, IMO. Check out this article: ------> As you can see, the vibration could be caused by: worn out spark plugs, broken motor mounts, loose or disconnected hoses, Faulty or Poorly Adjusted Fuel Intake System (This may be WHY Check Engine Soon light is on), or even a Faulty Timing Belt. Also, if your Traction Control Light is on, that may be a separate issue which I'd recommend having a mechanic look at...Weather is getting bad (Here on East Coast anyway)...Disabled Traction Control System is not a good thing when there's snow, black ice, etc. to deal with.
