Hey guys. I know the lumpy idle in the Z is caused by the crank angle sensor being an unshielded wire. Will a grounding kit stop the electrical interference and level the lumpy idle?

EDIT: Also, do you think the dealer will notice the black wires of a grounding kit? Cause if they will, I might as well color match them to my car. :nana:

well a grounding kit is "supposed" to smooth out the idle, but I don't know if it's true, but go for it....the dealer can't say anything about a little old grounding kit, get whatever color you want, they will probably love it! :wink: My dealer shows off my engine bay to the salesmen when I am there :wink: :wavey:

From what I understand, the CAS harness isn't an issue if you are NA. Only FI cars have that issue.

As for the grounding kit, it may or may not fix your idle problem. I would try it out anyway because it's affordable and worth the try. Don't worry about the dealer giving you the stink eye about it either.
