When the car is cold (engine temperature) the car runs perfectly.

Once warm, the car stutters on hard acceleration. If I keep my foot down it will misfire.

If I accelerate moderately the car runs fine.

I can drive the car at any speed, it’s just acceleration that I have the problem.

Hello my name is Dave.

The first thing we need to find out is if there is a trouble code, if you have a check engine light on you definitely have a trouble code but even if it's not on it is still possible to have a code stored. If you take it to most auto parts stores they can scan your car and give you the trouble code(s). If you could do that it would make it a lot easier for us to guide you in the right direction.
