03 Impala questions....

I have an 03 Impala.....3.4L engine....Im having a random proble with hard starting....sometimes have to crank 'er really good to turn over...also the high speed handling is crap....really wanders when you punch it on the highway.....I am just wondering if others have experienced this?....like to get some ammo before I complain

maybe you need a new fuel pressure regulator.
