timing chain and covers question & rough idle question.
Now my major issue and question is that I'm have a more than normal rough idle, it's throwing my knock sensor code last time I checked , I regapped my plugs to chevys new specs for the iridium from .04 to .06 helped out , but along with doing so one of my wires ripped as I was trying to take it out , I barley pulled on it , so I bought new wires because there original wires were old , there msd wires , saw a huge improvement idle , but still some what rough , my buddy thats also a mech told me it could be two things either my coil packs or my timing chain doubts that it's the coils so said best to try the timing chain , and read that its best to change between 50 and 70k miles any way. So what does every one else think?
I'm so sorry it's so long , but I figured just do one long post instead of a bunch . Thanx for every ones help
I have a 02 camaro z28 6 speed
