Hey guys, I drive a 92 Vigor GS.

My check enging light comes on regurlarly. Mostly comes on when I'm going down hills, or when I have a lot of thing in use, e.g. radio, wipers, heat, lights, etc.

Also, when my lights are running, the car starts acting weird. The lights on the dash dim when i come to a stop, and then when i go again, they return to normal. And when i'm stopped, the car will bounce up and down, as if it's gonna shut off, but then powers up right before it shuts off.
