2016 Mustang GT Startup Idle Misfire’s ?

[thegtway]

Hey guys I’m having an issue where my car sounds like it is misfiring upon a Cold start or a warm start it almost sounds like I’ve installed a cam and it wants to stall Also I’ve been tuned by Lund for almost 2 years with no other bolt on mods only a tune. This is an issue that just started happening recently.


Car is not throwing any Check engine light codes


I made a quick video to show the problem exactly

My only guess is it’s fuel related maybe bad fuel pump or injectors what do you think ? Also I’d like to add that this only happens when I start my car whether it’s a warm or a cold start. It will be greatly appreciated if you have any ideas or insight on what’s going on.

I see the problem, you parked next to a camaro. LOL All kidding aside, performance not off. I 'd change the brand of fuel for starters.

Only at start up, goes away after driving. How many miles on the clock.?

I wish it was as simple as changing fuel brands but this has been going on for about a month now so I have gone through multiple tanks of different fuel brands. I have about 56,000 Miles on the car.
