if you're close enough, I can take a look at it for you. PM me.
$1200 is waaay high for plugs. like mentioned above, if original, they're way overdue. I still think the not starting when hot is the cps, but would want to verify it first in person. Old brittle plug wires can cause misfires as well, at $50each, the dealer supply would make you want to replace them individually, but aftermarket complete sets can be had for about $180 last I checked. I have used them on a 2000 S430 I did plugs and wires on about a year ago and no complaints from the owner as of yet.
