Yeah I agree you should never boost the car cold, but it should be able to pull out of the parking lot fine just like any other car without missing and hesitating...........mine has the same exact symptom that he is describing every morning without fail. If the car did this the whole time I owned it that would be fine, but I drove it over a year and even in the dead of winter it never did this garbage to me. I am talking 10 percent throttle input on a 90 degree day and it doesn't want to go for the first minute or so of driving, almost feels like the car is misfiring or has bad gas, then it magically dissapears three blocks later.

^^ exactly that, I'm not boosting it at all when cold just simply trying to use light throttle thru a car park or even light take off when cold not even getting close to seeing boost
Replaced coils leads and spark plugs had battery tested today also had a diagnostic scan tool plugged in to see if any codes were logged all came back ok.
Next step is to clean MAF if problem persists... Hopfully not

Also one other thing I would check is the fuel injector resistor on the firewall. make sure all 4 of the prongs are solid.. I has one that rusted and broke somehow??? car would run fine until i got on it a little then it would misfire.
