There are a couple of things that will cause that symptom. DFirst check the fuel pressure that is is within spec at all times. The other thing that acts that way is the Mass Air flow sensor.

Not real likely. You can test that with a DVOM and look for an open spot in the range.It usually won;t have thjat much effect on the engine though.

Reply to Hammer Time's Post: Well I'm not sure what to do sense the fuel pressure is good and the mass air flow senser did not help this problem either. By the way the car runs great otherwise if you are driveing and mash the gas she takeds off just like she should never nissing a lick, this problem only happens at a stop then trying to accelerate, like form a stop sign

That's definately not where is should be so you need to follow up on that info and find out specifically what the pressure is..
