I did a big 3 aka upgraded grounds on my car for a system I'm starting and now when the car is idle it feels like the car wants to stall, I was told that's normal when you disconnect the battery and the car needs to learn all over again. Can anyone clarify this? Upgrade included:

-Negative on battery to frame
- negative on battery to engine block
- positive on battery to positive on alt

 

did you leave all of the original wires and harness in place?

ensure all the wires are tightened

if all else... remove the wires one by one (turn car off...remove one wire...turn car back on)

 

You did it right. That's not normal. Time to troubleshoot.

 

Yeah I even disconnected it all from the battery and it still feels like it wants to stall

 

Hey black Betty I actually have one of your grounding kits installed along with the big 3 do you think with the big 3 and your kit is causing interference or something ?

 

Nope. If you need it, more is better. But it sounds like you have serious overkill. All that you should have needed to add is a battery + to alternator cable.
