Foul smelling white smoke is almost certainly ATF.

Replace the vacuum modulator before it carbons up the rings and wrecks the engine.

Could it have siphoned AT fluid into the intake via a vaccuum hose or something like that? I had an issue with my old Suburban once that oiled up the air filter. It was because the PCV valve was not inserted into the valve cover. Not quite the same but sort of an odd thing to happen. Look for simple things first!

Subject: [MBZ] Strange 500SE Smoke Problem


All,

Last night I was going to use the 500SE to tow my brother's Sebring from
behind the house.  While we were finding a place to hook the tow strap
to the Sebring, the SE was idling and suddenly started BILLOWING a HUGE
cloud of smoke.  By huge I mean filling my entire back yard in 20
seconds huge.  The smoke was white, it didn't have a sweet smell
(antifreeze), and it didn't smell like oil or have a bluish tint.  I
can't remember/describe what oil smells like at the moment, but the
smoke had a mild bitter smell to it.  Almost a burnt smell.

The car was slightly nose down... I leveled the car out and turned it
off (after even more smoke from moving it!). Restarted it 30 seconds or
so later and it kept right on smoking.  Turned it off for about 5-10
minutes, restarted, it smoked enough to clear out the exhaust, and
didn't smoke again.

--The car is gray market so there is no catalytic converter
--There was no change in engine speed or sound
--Oil level is at the add mark
--Forgot to check coolant hoses when engine running, but immediately
afterwards they weren't pressurized (rad cap could be bad though).
--On the 600 mile trip from Kaleb's the car would make a slight haze of
gray smoke when it was floored (probably normal)
--Also on the trip from Kaleb's it made a big puff of white smoke when
accelerating from a stop sign immediately after getting off the
interstate. I thought valve stems at the time, but I don't remember if
the smoke was bluish or not.  I don't think it was.

Occasionally the car goes into fast idle for no reason.  Giving the
throttle a blip will return it to low idle. Kaleb could push on a black box (some kind of ECU) on the firewall and get the idle speed to change.
  Is this related?

WTF?  I know nothing about gas cars...
