This morning my ZX3 was working fine and I went to my buddies house. We decided to go out for a bit and it was working fine still but when we got back in it and tried driving back to his place there was a faint smell of burning plastic, the check engine light was flashing and the engine was shaking pretty badly. I just tried to leave his house and when I try to reverse it shuts off. Earlier this week it wouldn't start so we just charged the battery and it worked fine. Any ideas on what's going on? Are these problems related?
