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.

 

Good to know. Probably some other reason im getting 18mpg. The 2.5s really suck gas apparently. 18 city and like 25 highway

 

I installed a wire 3 years ago to proves that it is a MYTH about grounding the throttle body. If there is a problem, it is due to a connection issue at the connector or the connector mate on the throttle body itself. Attaching a ground lead is like placing a Band-Aid on a cut that needs stitches.
