ROUGH AROUND 2K RPM
 

2015 FRS WITH ABOUT 1750 MILES. I WAS WARMING UP MY CAR THE OTHER DAY AND NOTICE THAT AROUND 2K RPM THE CAR WILL FEEL LIKE ITS MISFIRING. WHILE IDLING THE MOTOR AT AROUND THE RPM IT RUN ROUGH, MAKES ME CONCERN. WILL BE BRINGING IT IN SOON TO DEALER, JUST WANT TO HEAR FROM OTHERS.

DID YOU START IT COLD? THESE CARS WILL RUN A LITTLE ROUGH WHEN THEY'RE COLD

IF ITS A COLD START, ITS NORMAL. I WOULDN'T WORRY ABOUT IT AS LONG AS YOU DIDN'T GET ANY CHECK ENGINE LIGHT.

Why are we yelling? Are you guys outside?? Mine does the same since new. On cold starts in sub-freezing weather, the engine will make a pop sound during the first 45 seconds and idle very rough.

IT IS FINE. NORMAL COLD START.

NEXT TIME WHILE IN YOUR CAR, REV THE RPM UP TO 2K AND SEE IF THERE A FLUTTER OR BREAK UP IN RPM. SLOWLY RUN THE RPM UP, SHOULD BE SMOOTH THROUGH ALL RPM. WHERE TO MINES AROUND 2K IT STARTS BREAKING UP AND CLEARS BACK UP AT HIGHER RPM. SOFTWARE UPDATE OR MISFIRE... BUT THERE NO CODES

HMMM... I WILL HAVE TO TRY THIS NEXT TIME AND SEE IF I EXPERIENCE THIS ISSUE YOU SPEAK OF.

YELLING TO GET OVER THE NOISE OF ROUGH IDLE FROM THE COLD START. (IF THAT IS WHAT IT IS SINCE I CAN NOT POSSIBLY DIAGNOSE AN ISSUE FROM A COUPLE OF SENTENCES ON A FORUM)

:lol:
I should of saw this post coming by the look of the title all in CAPS :bellyroll:

LOL IM NOT YELLING THIS IS JUST DEFAULT. DIDNT KNOW THAT USING CAP LETTERS, CAN HURT FEELINGS. AND THIS IS NOT A COLD START ISSUE. YOU MANUALY NEED TO REV THE UP THE RPM AND CHECK FOR BREAK UP THROUGHT THE RPM. JUST NOT KNOWING THE REASON ITS DOING THIS JUST BUGS ME BECAUSE MAY NOT KNOW WHAT IS TO COME OVER TIME.

Caps is generally reserved for yelling and it perturbs some people (personally I could care less except that is slightly harder to read).Like you said in you first post it needs to go in and be checked. Anybody that tries to diagnose over the internet is guessing at best and could get you all worked up with horrid scenarios when it is really a 5 minute fix (or not broke in the first place).

I COMPLETELY DISAGREE. THE INTERNET IS A MORE RELIABLE SOURCE FOR DIAGNOSING YOUR FR-S PROBLEMS THAN USING THE WARRANTY WHICH COMES WHEN YOU BUY THE CAR AND HAVING PROFESSIONAL TRAINED TECHNICIANS LOOK OVER YOU CAR.

im just a owner wanting to share my encounters, may help some. just trying to do my part to help the community as i will figure the problem to make this a better experince owning this car.
