stuttering problem

[Zaun]

So my motor is having a stuttering problem, But only seems to be happening when i first run the car. For example say i jump in the car in the morning start her up take off to my destination my car will stutter at middle to high rpm's. After about a min or 2 it progressively gets better until the middle range is perfectly fine and then after 5-10 mins the high range is great too. Now if i park the car for an hour or 2 i dont have the problem again but if it sits too long i have the problem again. Any ides?

My first suspicion is that there are one or more intake leaks causing a lean cold start mixture. Find a shop that can smoke test the intake and fix any leaks found. There could be other causes, but there is no sense in pursuing those until it has been proved that there are no intake leaks.
