Maybe someone else will chime in on this too - but it sounds like the car is starving for fuel in first or at low RPMs. This not a problem that I have, and I'm surprised that you're not throwing a code. It may be as simple as cleaning your MAF sensor. Do a google search for MAF cleaning - the sensor is delicate, but it's a simple enough job. I'd try that first - if it works then you've got it fixed. If not, then check for a code. Maybe you could get a code reader or have someone check it to see if there are any codes stored in the system.
