You might be right but I think new or better quality ground wires also help. My 15 year old ground wires look like they have seen better days.

Do the conductivity of the factory ground wires deteriorate over time and exposure to the elements?

If you understand why the high end stereo guys use very thick cabling and why the amplifiers with good contacts and milspec wiring perform better, then you should readily see why this would be the case with grounding.

Thanks for the confirmation. I'll save that for a future project.

I have no idea what that means.
I have so much to learn about electronics...

Keep in mind that one of the grounds that goes to the block (driver's side bottom of the front iron) comes from the body wiring harness, which barely any of us have replaced.

question, does it really matter what points you use (adding more ground wires, not talking about stock wires)?? i just threw in some grounds but not exactly where damian? and you put them.. essentially just adding more grounds will help right? i did the UIM to brace by intake filters and Back of UIM to front (dotn know if that will do anything)
