I have a 92 Camaro 305 TPI automatic that is all stock. I thought that I was having an issue with the lockup switch but messing with the car in the driveway I don't think so anymore. Most of the time the car will die when I put it into drive or reverse and take my foot off of the brake pedal but when it will keep running and I drive it down the road it will buck and about die and come back up over and over. Well the other day I was in the driveway with it and was not using the brake pedal at all. I could leave the car in neutral and let the car roll down the driveway not using the brake pedal at all just using the e brake handle. It runs fine in neutral but once i let the car move at all even in neutral it dies ( again no pedal just e brake). I am thinking something with the vehicle speed sensor or speedo sensor. Leaning towards the VSS. If anybody knows about this please help me out. Thanks.
