Possible fuel pressure problem. Please help

I have a 1995 chrysler cirrus lxi 2.5L V6 engine. When I start driving, it stumbles like it's either not getting enough fuel or too much, then when the tachometer reaches almost 3rpms precisely each time, it takes off like it normally would with me giving it that much gas. I'm thinking maybe fuel pressure regulator, but I don't know. Any help?
