Idling hard and accelerating with foot off the pedal

[Dawood]

Forgive for iam new to the SHO and forum. I’ve had my car since November 2018, purchased a 2015 non pp with 28k on the odometer I now have 30400 miles on it, I have not yet done any fluid changes at all last I checked a few hundred miles ago it was fine.There is a few things that concern me about the car. Sometimes under low speeds I will give it gas maybe wot or half way and it will hesitate(I think that’s the correct term) it will sometimes pick up And then drop in a millisecond or not go at all. Another problem I’ve had lately is it will sometimes idle very rough after a few minutes of warming up and then calm down, I’m really not sure if that’s normal or I should look into it. Also I started it up and when I shifted into drive the car drove as if my foot was on the pedal and in reverse also, it was going at least 2mph by itself. It’s the first time this has ever happened to me in any car and I’m not sure what the cause is.

When troubleshooting computer controlled vehicles, always check codes first. So that is what I would do, pull codes from the PCM. A local parts store can do this for you if you do not have equipment yet (OBDII adapter + software for your smartdevice).

Stock or tuned? Any outstanding recalls on your vehicle (owner.ford.com)? Possibly a Fuel Pump Control Module, out of many possibilities.

I do not have any tunes, I took it to pep boys to get it scanned like you suggested and no codes

My first thing to do after checking codes is to change the spark plugs if they are not that new. You will get fresh ones in there and you can get a good look and see if there are visible clues on why it might be running less than optimally.

Above post is good to check for potential recalls. Those will also let you know what to keep an eye out for in the future.

If you still have a factory warranty you can pursue a dealer service diagnostic (cost out of pocket if nothing is found) in the hopes that if something turns up it might still be covered.
