I had this same issue. I got open flash tablet and the stage 1 tune fixed it!! I took off the tune a couple months later and sure enough the problem came right back without the tune
I sprayed lubricant on the pulleys attached to the belt and it made the idle smoother (not as noisy) and fixed the idle issue (mine was with the AC on).
I will, and I hope it's something they can figure out. Because nobody has had a strait answer from toyota or Subaru. It's random parts or random CEL's being thrown that aren't consistent with what everyone are experiencing.
i was thinking A/C kicking in but its a bit heavy for that... but try battery and or taking the battery out for a few hours to reset the ECU. make sure you also have good gas in it and see how that goes...
I don't know if u have found out what the problem is but a Toyota dealership has. U were right it is a tweak that was needed to the ECU. Many people were having this issue and it took Toyota a good 3-4 months but I guess they found the issue. Check FRS forums out there more info there. At least they have an official fix now.
Same thing happen but only now it almost stalled. And when it recovered to normal idle check engine and traction light dame on. Took to dealer said it threw a code p000A. So left the car and they gave me a renral for further testing. Something about the vvt/ cam
5 years later and I think i’m in the same boat. Same lights on but my frs stalls at low rpms ie in traffic and at lights. What was the final diagnosis for yours ?
I used to have this issue till I tuned my 2013 and put headers on it. Changed how it idles and revs a lot better than it did. In my opinion this car should be tuned higher than what it is. The torque drop is horrible in these cars and was a major complaint I had with it. I just bought a tacoma and am gonna drive my frs less now. It was fun and atleast has been reliable for 200000 km.
My advice is you sould check your coolant level, if its less than low than add some so its like a half of inch more than low and than if it wont helps than you should go get your ECU Remapped. Goodluck hope Ive helped.
The ecu learns and adjust to how u drive the first 100miles and stays that way if you drive different like city drive from track then valve time might be more adjusted for one, its no biggi i dont knw what everyone is complaining abt. get an ecu flash or im sure if its left like that wont cause any issues. its in no way mechanical
Well it has been a bit since i've posted this. Still the same shuttering and dip. But i haven't thrown and CEL's or Broken down. I'm hoping and this is odd to say that maybe its a manufacture tweak in the ECU.
Vasik Vasin After driving on the freeway it would fluctuate heavily. As well as when using the A/C. I sold the vehicle after owning it for a year. The idle and the High Fuel Pressure Pump (w/chirp) were too annoying.
Initially that's what I thought. Toyota has officially diagnosed it as a (High Fuel Pressure Pump) issue. Since that point a few years ago now I got rid of the car because they were not able to fix the vehicle. I traded it in for a used Tundra, after I moved I sold the truck and bought a 97' Miata with 23k on the clock. ;)
I was curious what was inside the pump that was causing the actual squeak. A tuner that builds Subarus up at a shop called All Apects Motorsports said it was a spring inside. Now I don't know exactly what causes this spring to fail, or if it is the only part failing?
Hey guys this goes out to everyone.. I was going to trade my scion tc towards a used 2013 frs.. The frs is a "lemon" due to this idle issue.. is it a fixable issue? is it bad? the frs is $19,000 25k miles.. 5 axis kit all the way around.. clean title.. toyota bought it back.. let me know your input and opinion..
@@MineCraftQhead turns out when I was getting the cars clutch changed, the technician noticed the tube to the air box wasn't secured all the way and it was causing the rough idle and stalling. As soon as he secured that and made sure it was tightened completely (no leaks) the car idles perfectly. Double check all your tubes that go to the air box, as well as the MAF sensor and any exhaust leaks/ worn exhaust gaskets, definitely could be any one of those. Hope that helps!
I believe the problem is A/C idle fluctuation and it is fixed by the dealer flashing to a newer "BO1C" or higher calibration ID for the ECU, or getting the stage 1 tune from oft might fix it too.
There are four or six different idle control tables that the ECU switches to depending on load situations. The earlier calibrations for the ECU had the idle set at different rpms for A/C or other situations causing an inconsistent idle that could fluctuate from 600 rpms to 750. I think the newer calibrations fixed this by setting the idle to 750 across the board.
I have the FT-86 2014 and i have the same issue and in extra when i drive the RPM lags on 2500, 3500, 4500 and when it reaches 5000 it speeds and shifts up when it reaches 7000, i use 98 octane every check up i have done was in Toyota's official workshop in the UAE after the 22,500 km check up when i received my car back it happened the first time when i gave it back to them they reseted the computer then after 30 km of driving it happened again then returned to them and kept it for two days to check what is wrong, they cleaned the throttle, they checked the gear oil and everything then they found out it is from the injectors it has to be replaced so now i'm waiting for the warranty department in Dubai to agree to fix my issue after the vacation we will see what happens.
This is unfortunate to hear, having the 2014 model doing this is odd. I would of thought they worked out those bugs by now. Do you have the Lemon Law where you are at? If you do, make sure you document the labor you have Toyota do on the car. Once you have enough time into getting the car to work see about getting a lawyer to represent you in the case you may establish. Getting a refund or a new FT-86 may be needed. Good luck!
is it like the dip only or what else you felt like changed? like does it run good when you start ..like your clutch and such???..Because i am have issues with my BRZ, but idk yet what it is exactly. i m thinking my clutch but i m not sure.My idle seem to act weird. but at the same time my clutch, like it use to engage easely when i lift my foot a bit . now its only engages really high, and i need to give it a lot of effort for the car to go...like high revs, like it lost power. so i was thinking maybe its clutch or maybe its caused by the iddle issue too. IDK.
+RayddenPrimeTV If you bought this vehicle used, it is entirely possible the person before you botched a few gears while shifting. Or you botched a few gears, I'm not sure of the vehicles history. The issue of your transmission would not be tied into the High fuel pressure pump faulting out. Take the vehicle in to get looked at, best be safe then sorry. Good luck!
i think i have same problem, when i rev it at neutral stays 2k rpm for sec and goes up. it would jerk on high torq low gear 1000-3000 rpm. and turned on the car yesterday just sitting and idle went down almost stalled and CEL turned on
sean c yo!! Thanks dude. I know your comments 5 years old but I was so worried my gaskets or something was wrong. Nope. AC was on. You have any idea how to fix this?
I had this same issue. I got open flash tablet and the stage 1 tune fixed it!! I took off the tune a couple months later and sure enough the problem came right back without the tune
Really?! Well finally theres something that works. Do you know what in your tune that adjusted it, more fuel pressure at idle?

Got a 2018 86 and having around the same issue and the gave a recall for fuel pump does anyone know if it will fix it
That's terrible, I didn't know if that was still a thing that late in the model year. shame.

It's because you have your ac on and it's drawing power when it cycles. Youre drawing a load. Small battery small alternator

Unfortunately unless there is a CEL, there is no re-flash for it. So when decelerating and sitting at idle the car will sputter. YAY Scion :/
Does your idel drop below 500rpm? And does it fluctuate between like 600 and 400?
Vasik Vasin After driving on the freeway it would fluctuate heavily. As well as when using the A/C. I sold the vehicle after owning it for a year. The idle and the High Fuel Pressure Pump (w/chirp) were too annoying.
sean c that normal chirp for that car and the fluctuating would be a air leak

sean c i see i know that a high pressure fuel pump it makes chirping noise that just cause of how the fuel system is set up.

There is a coincidence with the AC and the dip, however it does it when decelerating.
pray that its because of some load, fan clutch or compressor kicking in. Good luck and please update
im late but did you ever figure it out?
Sure did. I sold it. I attempted to lemon law it, but they said it still ran within specificities. So i just bought a Tundra.
I'm super late but my 2013 BRZ has this same thing even with an OFT tune. There are even times that it stalls out for me

How to fix it bro ?
@@josephgoebbels0 went to mechanic and they changed a sensor then referred me to go to a tuner and tuner fixed previous tune
Okay so what octane rating is the gas? I'm using 91 highest available. I have the same problem and mine started after the first oil change.
Well if it wasn't a big deal then there wouldn't be so many enthusiasts complaining about this, this is not supposed to happen.
TSB was put out for this there was an ECU update to fix it.
it only happens to me when the air-conditioner is on. if it's off, it doesn't happen.
Dragrede mine too bro, is this normal? My RPM fluctuate 800-1000 with AC on. Have you fixed the issue?
Same here ???!!!!!
its not a nissan.... the idea of the car is based around the AE86
It happens with out it on as well.
The Timing and the AC do not work well together, i wish it was as easy as that though.
sean c yo!! Thanks dude. I know your comments 5 years old but I was so worried my gaskets or something was wrong. Nope. AC was on. You have any idea how to fix this?
Yes, it's not a nissan. It's not heavy enough lol.
Well i'm running premium, however who knows what quality it is?
Did you ever find out what it was
High Fuel Pressure Pump.
@@seanc5481 not the fuel pump right
check ur octane rating for gas!
I have 2015 frs at 19000miles, forgot to say that and only use 91 octane
I gotta say that I'm surprised they haven't fixed this issue this far along into production. Did you buy it new or Used? I also used 91 at the time.
Fuel pump or high pressure pump
Right. When it was initially being diagnosed by Toyota I was told the High Fuel Pressure Pump.
Check your battery charge
mine chirps has the idol issue and now my engine light is on
I fixed Mines buy using new Denso spark plug nee coils and new ecu flash
Yeah I'm working on that and in deeper detail.
Ignition coils
Did you find a solution to this?
No I sure didn't, I sold it. a year after purchase. I heard that changing the idle rpm fixed the noise. I don't know about the issue.
There is a TSB for ECM update.
