I had a similar problem one morning when I blew the injector out of 
the engine.  The car started very rough and wouldn't run without 
revving the engine.  When I finally looked in at the engine.  I 
noticed the injector was just blown out.  I changed the o-ring on it 
and put it back in place and have yet to have a problem.  But it was 
one of the strangest weirdest things i have seen.
