i grounded my throttle body today and drove it around the block and he car died and wouldnt start back up any one else have that problem???????????

 

is all of your wiring ground properly? did you scratch some paint off where the wire-ends should be touching bare metal or did you buy a kit that you connect all of your wires to that device?

 

went right to the negative on the battery

 

Remember, Mazda 6's are "drive by wire"

This means there is no cable that connects the gas pedal to the throttle body.

The throttle input works on a voltage reading, much like the mass air system used to measure the fuel curve measures the air and coverts the signal to a voltage.

Simply answer, it it probably not a good idea to ground your throttle body with a "drive by wire" system.
