I drive a 1995 Chevy Cavelier about 78,000 miles give or take, and while I was at a light the engine shutoff, figureing it just stalled I tried to re-start it, but the instant I put it back into drive it shutoff again, I try this several times I try giveing it gas everything, as some as I put it in drive it shuts off. So I push it into a parking lot, and mess with it for another 10 minutes atleast, same thing, but everything else was working, the engine started fine, and would even rev, but the instant I shifted into drive it shut down as if the keys were turned off.... So I give up and walk about 2 hours home, I get a drive back up there with my Uncle thinking maybe he can figure it out, he gets in, puts it in reverse, then shifts into drive, and wouldn't you know it works fine, and I look like an idiot, I'm not sure if it was putting it in reverse, or sitting for a awhile that did it, but I don't really want to try driveing it again untill I find out what happened, so whats wrong with my car?....
