Hesitates when cold

[theman33b]

I have a 91 camry 2vz V6 when i go to drive my car when its been sittin a long time i cant take off as fast. I go and start up my car and let it warm up for like 5-10 min and then take off and it almost wants to die when i go from a dead stop. It never has died but it seems like it wants to. I have run injector cleaner, new cap, rotor, plug wires. I dont know whats wrong with it. When it warms up a little bit it runs fine and it doesnt hesitate except from a dead stop never does it when im moving. sorry for the long post but im in need of some help. thanks

1) vacuum leaks
2) ignition timing

Yup, having same problem. Started to happen after the timing belt was changed. Car is absolutely fine when warm but runs like a dog from a cold start. Have new Sparks, HT leads, O2 sensor cleaned, cold start injector cleaned. Given up at moment as really don't wanna spend $ to get timing rechecked if it turns out not to be that.
