...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: http://www.carsdirect.com/car-repair/5-causes-of-engine-vibration ------> 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.

So we have a 2002 Pontiac Sunfire, 2.2 litre. Bought the car, used it not even 24 hours later the battery light came on, did a multimeter test, showed the alternator was bad, bought a new one and changed. Worked good for approx a week. Now the battery light comes on and off. When the battery light is on, the wipers are slow, the stereo quits working, when idling the rpm's will drop down and before stalling jump back up, all the lights on the dash will light up (battery, abs, e-brake, airbag etc.), the speedometer and tachometer will quit working also. ANY IDEA WHAT THIS COULD BE??? 3 Answers
