Grounding throttle body for Cobalt LS

Does anyone know if it is possible to ground a Chevy Cobalt's throttle body despite having the remote access terminals in the engine compartment instead of the actual battery? And is the throttle body even able to be grounded? This link shows it being done on a Mazda 3 but can the same be done on a Cobalt? Thanks.

Well the fact that the battery is in the trunk is irrelevant.. The entire chassis is grounded. So in theory you could do this, but I doubt it would do anything..

hmmm. well on the mazda site, many people report that grounding the throttle body makes a small difference in the briskness of acceleration. I figured i could at least try it, but i'm not sure if it'll damage anything

ya and i can't even find the bolts to the throttle body to attach the wire to... I just thought i'd see if it was possible with the cobalt. just adding a single wire to the engine sounds too good to be true

There are 3 bolts right on top you could use. Then run the wire virtually anywhere that is grounded. Let us know if it works out for ya. After reading that whole thread i think it just might do something.

i did notice three bolts on the left side of the engine compartment. the three bolts on the right side are for the negative remote terminal. are the three bolts on the left side connected to the throttle body itself?
