tonight, while I was driving, all of a sudden the battery warning light and the handbrake light lit up.

Then, when I was in neutral, the car started going from 1000rpm to 1500... in rapid succession.

an hour later, the check engine light is also lit up and the sound is really strange... when I listen in the back I see the engine doesn't seem to be running smoothly at all.

now, it kinda stopped going from 1000 to 1500 but stays at 1200... when in neutral it's usually 800

anyone had this happen??? Just taking a chance if someone might know what is happening

by the way, I have a 2003 cl-s 6-speed
