Alright I have been reading posts about certain cylinders misfiring and all, but I was wonder how do you determine which cylinder is misfireing? Also when I am sitting idle I think that my timing is slighty off ... would like to fix this if it is simple to do any help would be appreciated! :boogie:

You tell through the OBDII interface, either with a tech2 scanner or via a custom interface to your PC and some OBDII software/hardware. The on-board computer of the engine knows which cyl misfires.

I just took mine to a shop. I had misfire in cylinder 1. Replaced the injector for $500, then then next day had misfire in cylinder 3. YAY!!!
