I have a 92 s10 blazer 4x4 non vortec. Almost every time i crank it up and shift it into reverse or drive the car dies and also the battey dies alot. I have to rev the motor and shift into reverse or drive just to keep it running. Has anyone else had this problem before?

 

it could be your transmission sensor. im not sure what the sensor is called but i had the same exact problem with a buick i owned. when u rev it up it bypasses the sensor. u can disconnect it and it will run fine but will idle a little higher and use a little more gas.
