I figured my occasional bouncy idle after pushing the clutch in when coming to a stop could be at least partially fixed by cleaning and/or replacing my ground wires. There is an obvious one coming off the front-right corner of the block to the frame by the driver's head light. (I have a 95 Civic EX with the D16Z6.) It has 140k miles. I was wondering how I would go about cleaning it? Or even better, what wire should I use to replace it? Should I just buy a kit? And where are all the (easily-reachable) grounds? Sorry for all the questions. I tried the search but it's not very helpful. I heard that 8 gage wire should be fine, but I'm not sure how I would crimp it and enclose it with rubber insulation. Thanks Honda Tech.

 

Sandpaper.

 

IACV.

 

Yeah is that easier to clean than the FITV? I tried taking my FITV off a month ago to clean it and almost broke my wrench trying to loosen the seized bolts. And then I couldn't reach the third one (driver's side one) so it was all a waste.

 

Going up.

 

This crazy trick I learned was using coca cola to clean off the corrosion and other miscellaneous build up. As for the mounting point where the bolt actually hooks the wire to the chassis, use sandpaper as Grumblemarc stated.

You absolutely could buy a kit of just thicker wires. But it will pretty expensive compared to just buying a REALLY long wire and making your own measurements for your cars ground wires. I have 4 gauge wire for my grounds, MIGHT be overkill, not too sure. I know 8 gauge will at least improve a bit.
