My recently rebuilt engine [ 2000 miles ] is having a warm up problem as

well.  After initial start up - the engine slowly drops to a rough idle then
to a stall.

the problem disappears when the engine is warmed up.

I *believe* I have pinned this down to a fuel injection temp. sensor on the

plastic thermostat housing. Your problem sounds a bit different but

it is one place to start.

        Volks,
        I've got a brand-new (~3000 mi) 2.1L that runs like a champ once
it's
        warm.  Here's the mystery problem that only happens when the bus is
        started from cold:

        1) runs _roughly_ for the first two minutes or so
        2) exhaust smells like fuel during that time
        3) six out of ten times, the engine abruptly shuts off about thirty
        seconds after startup.  No warning, no drop in rpm, just screech!
and
        it's off.  It starts right back up and idles fine after that.

        Often, once the engine gets revved to over 2,000 rpm the rough idle
        disappears.  Where do I start troubleshooting?

        Best,
        d.
