Thanks Gilly,

I would rather do the plug change on a cold engine, too, for the same reason.
But, the thought of breaking a plug off on this engine is kinda scary.

I posted a sunroof query awhile back with no response. I've removed the roof, greased the cables with the proper grease, replaced the cable cover plates with the new "2 hole" plates, but the cable still escapes the track when the roof is retracted. I think the cable was weakened from all the kinking that occured prior to realizing that I needed to service the sunroof. Anyway, I think I need to replace the cable itself. My question then and now is whether or not I would need to remove the headliner to replace the sunroof cable or whether it was accessable from the top with the sunroof removed.
