97 Outback sport (2.2) "hesitates" sometimes.

[Josh Assing]

sometimes, after starting the car, and putting it in drive, it sorta hesitates,
almost like the engine dies, but it doesn't and once it clears up; it doesn't
happen again until you shut the car off...

Any ideas on what it could be?

PCV Valve and/or vacuum hose are my first guesses.

Possibly fuel pump or fuel pressure regulator. Try turning the key to the
on position for a couple minutes before actually starting the engine, see if
that helps.

I think someone posted a similar symptom on the USMB forum that occurs
if you accidentally or by habit feed a little accel. pedal when
starting. Seems the ECU will set an advanced throttle position as it's
new 'zero' point.

I'm sure there are other problems that could cause you symtom too.

thanks. I thought of that; but wouldn't it happen more often than once?
it's not temperature related... at least it doesn't appear to be...

I'll double check vacuum and pcv.
thanks

that could be it! I'll have to make a marked effort not to touch the peddle..
the car is my wifes and my car is older, that needs a little "help"

Doubt that; as I often let the car "warm up" in the morning for a little so the
car is slightly warm for us.... but I'll try.
