i would pick up carb clean and spray the throttle plates. just a little carbon will ef it up. when you spray it, try to have a towel in there to soak the crap up. it will run rough/not start at first but that is normal cuz its flooded. update tomorrow on how its going. those 3.4l's always suck when its cold. mine would hesitate real bad when i initially stepped on the gas in drive. it was just a split second then it was fine. idled fine too. never fixed it though, bought a z28 instead.
