my new replacement rotor fell on the floor and a chip near the metal piece on the side wall of it chipped of
was wondering if it would make the spark arc or something? because the idle and stuff seems worse then before.. i replaced it and the cap because of only 4000 volts to cyl 6 and 8

 

Theyre cheap enough that Id replace it. Cap and rotor are pretty important to make sure they are in near perfect condition.

 

there brand new, Problem is replacement one fell on the floor real quick
it just cracked a piece on the side wall

 

Yea, thats what Im saying, if it got damaged at all, I would replace it. Its cheap and not worth chancing.

 

Without a doubt, the rotor falling on the floor more slowly would be preferable. Perhaps moving to a location with a lower gravitaional attraction would be advantageous. Or, carpeting the garage could be a temporary safeguard until you can arrange the relocation.

In other words, bite the bullet and get another rotor. If it's more of a scratch than a crack, it might be servicable. Have a photo?

 

lol Nah but lemme draw something in paint hold on! nvr mind imt to ghetto/dumb to uppload it either way bassicly u know the wall around the thin metal strip the circle one, well a big chunk of it cracked out.. Im guessing like most times gm didnt put the cirlcular wall there for no reason so therefore.. guess ill be buying a new rotor

 

Yeah, a new rotor will be safest. About a lifetime ago, I had a Cadillac towed off the tollway when it died coming out of a toll booth. It was about a $150 tow bill to go a couple miles (just to get it off the interstate) for a $4 rotor that broke down the middle. Freakiest thing that I ever had happen, and I don't think I dropped it (it had run over a year with no problems - it just let go).
