i have this same problem. i've tried injecter cleaners, cleaning intake, got a new MAF, changing sparg plugs, and other things i can't think of right now. it is fine when it's warm out though. a mechanic told me i just have a rough starup. after like 5 min of idle on a cold morning, it runs fine. the next thing im gonna try is new wires, hopefully this will kill the problem.
