Throttle Body Ground Mod

http://forums.focaljet.com/duratec-t...-up-grade.html

I just did the mod where you ground the throttle body to the battery ground and it does feel like the car is a bit more responsive in initial acceleration.

I just want to know if there is ANY possibility of this having any negative effects on the car in any way? From what I understand it should do absolutely no harm.

oh boy...

but no negative effects...

and any positive effects are highly debatable... i think it did a bit for mine, but eh, some people don't notice anything, others do...

on the 3 liter duratec it gave like .5 but that prolly due to dyno error, it does help response tho.

if you need a grounding wire, i got some in red left over

Yeah, I know there's been quite a few healthy debates on the subject but if it causes no negative effects I figured why not try it?

It does seem to make initial acceleration a bit smoother. Placebo effect maybe?

Total placebo.
No effect can come from grounding the throttle body. Isn't it plastic anyways?

I did it on my 2009. Total placebo effect. I took it off, never noticed a difference, put it back on, no difference but I just let it there anyways.
