I'm not sure if this adds any usefulness, but reading Erik's last post about a possible slow leak after the engine is off made me think of it. On occasion when I turn the engine off, go do something for an hour, then come back and start driving away I have a noticeable stumble / hesitation in 1st gear that feels worse if I stay in 1st and apply more throttle. After shifting to 2nd the "stumbling" goes away and everything is fine. It doesn't happen all the time. Sorry if this is a red herring.
