Unofficial - CEL/SL/Idle Issue List for FR-S/BRZ Owners

[Rob_g]

I got my FR-S back today with a new ECU. So far it seems to run like it should now and the idle dip appears to be thankfully gone.

By the way, the TC loaner I was driving had idle dip almost as bad as the FR-S.

Not sure if there are older ones here but would like to know.

For toyota it's not a reflash, but an ECU swap. I would recommend getting the update. Sooner or later you will probably get the CEL if you have idle dip.

Interesting considering they are two entirely different engines. (or similar cams?)

Haha yeah that was my first thought too. But engines can have a rough idle for a number of reasons. In the case of a loaner vehicle I'd guess that it takes a fair amount of abuse and isn't maintained particularly well.

Not sure what to hope for at this point but I may ask if they can drive it home and back a few days to be sure it doesn't resurface right away at least.

I have a feeling I will be waiting for a new ecu but I won't know for sure until tomorrow. What a birthday gift that will be

on the twelfth day til' lemon law my subiee gave to me......

Well it's past midnight in MD so HAPPY BIRTHDAY ftc!! :happy0180:


Hopefully your birthday gift from the dealer will be your car in perfect working order

I guess I'm #132: howiedoit, manual FR-S, 4100mi, 7066xx, at dealer waiting for new ecu, Pasadena, Ca.

I dropped it off to Pasadena Toyota/Sciodn today. They're expecting the new ecu in about 10 days. CEL came on, on my way home from 86fest at 4100 miles, but I did not notice any abnormal idle issues. Everything felt ok, but I do have the chirping. I changed my oil with Subaru oil and filter at 3000miles.

I'm keeping my fingers crossed. They set me up with a rental from enterprise...a Chevy Sonic. It sucks.

Had the typical hunting idle, near stalling, and a weird clack-clack kind of noise i have not heard before from the engine before but have heard in videos of the issue. No CEL as of yet though.

Anyone know if there's a cold start injection loop on this system?

Will the day ever come that I can stop staring at my tach at every stop light?

The dealership also told me that if my FR-S has the problem that Toyota would send me a letter. Just curious, did any of us receive a letter stating Toyota screwed up and would like to be proactive and fix your car?

Well even though the TC had idle dip, it didn't feel like the engine was shuddering as it dipped.

Oh and I posted last night that I thought the idle dip was gone on my FR-S after the ECU swap. Well it was back this morning and when stopping I could feel the engine shuddering for a second or two. This is the exact same behaviour the car had before so I am NOT confident that the ECU swap is the answer. I am concerned that it's not a question IF the car will stall or the CEL will turn on, it's WHEN will it happen. I don't like driving a car I have to have these concerns about.

At least one person did; see post #1344 ITT.

That would almost be the best bday gift ever! 1st being born of corse...lol

[Alienate]

Toyota is NOT replacing every ECU with over 100 miles on it. That is BAD data.
My FRS had a direct from Toyota reflash done over the internet two days ago. It had 600 miles on it at the time.
The Fix has had more than 100 miles driven on it now.

My idle is a rock solid 650 rpm. no hunting, no dipping.


You guys should tell your service adviser about this fix. Why wait for a back ordered ecu?

Leave it to me to get this thread off topic! Well it's good to find humor in it somehow.
Most girls cry on their 33rd bday cuz they feel old, I woke up crying cuz I saw a loaner parked where my brz should be...meh

Status: waiting with baited breath to get my car, will leave work to get her cuz it's my bday and I'll do what I want (cartman style)
