Weird Rattling
Before my car warms up (when I first start it up in the morning) I can hear a strange rattling from under the hood on the drives side any ideas of what it can be?

Hmmm...
I had the same sort of rattling in My Turbo II, but it was actually in the dash (malfunctioning gauge)...
If you get someone to rev the engine with the hood open you might be able to track down the sound better. (I tracked a bad squeeling sound to a dying air pump bearing).

You should be able to disable the AWS by starting the car in gear or by disconnecting the water thermo switch at bottom of radiator.
Does it rattle even when you're seating in the car in a stand still (car not moving) past 3,000 rpm (is that what you're saying ?)
what kind of rattle (like metal tapping on metal) ?

Hmm, I just went out and started up my car right now and no chatter, only when the AWS activates
Good thing is the engine has never had flood problems

knowledge junkie
if it happens only at certain rpms (ie certain frequencies) then it's probably a heat shield. The one around the exhaust manifold on the NAs tends to crack around the bolt holes, and then just rattles.
