Sounds like what my car's doing at the moment, though I haven't been able
to connect it to either a hot or a cold engine. Sometimes it starts
perfectly several times in a row, sometimes it's the devil's own job to
start. It always starts in the end though. It catches, turns and then
stalls again (on the first try)- then several cranks with no result, then-
vroom.

Runs perfectly after that, no noticeable loss of power or rough running. I
did pour a bottle of injector cleaner down the (full) tank recently. Could
I have dislodged something? It's still in there, didn't fully empty the
tank yet.
