I'm far from a pro on these, but to me they don't look that bad. They definately shouldn't be breaking when pulling them though, did you use a torque wrench and did you check to see if the gap was right when you removed them?

i didnt use a torque wrench when i removed them...and it was like they were seized in there or something so some of them broke off...i replaced all of them and put anti-seize on the threads...didnt cure the rough idle

surprise, surprise...they looked normal. Its probably gonna be one of the stupid ass sensors acting up causing the rough idle.

:word:

They look normal to me too. Have you looked at your cap/rotor?? Any certain times it misses/runs rough or all the time no matter what?
