Hey guys I recently discovered this issue when I was on my way home from work and I was coming up to a red light I was going about 45 50 and I had to stop suddenly because of the person in front of me and when I did this the rpms dropped very low around 1kish the engine started to shake and the car shut off.the car is tuned with a perrin Cai, uel header and perrin 2.5" cat back. Any ideas? It does not always happen when I'm coming to a stop only when I need to suddenly stop.

Do you have the regular Perrin intake or the big MAF one?

I have a AT. I can pull a 180 backing out of my driveway. About 1/4 the time my car stalls. My car is stock. I know this doesn't help, but I sympathize with you.

Abe1120 · 02-05-2016, 04:24 PM

But the thing is I'm having no idle issues only when I'm coming to a stand still

KGFRS86 · 02-05-2016, 05:13 PM

I've had this exact same issue happen to me, for over a year now. I have an ECUTek tune from one of the best 86 tuners on the platform. I've had him review logs when I stall and my engine is performing perfectly.

To me, sometimes it feels like it's (torque converter) having trouble disengaging from something fast enough.

Using ECUTek I believe all my ECU software is up to date, but I'll have to double check the transmission ECU.

2013 FR-S
K&N Drop-in Filter
Intake Pipe
Moto-East Flex Fuel
Tomei UEL+Tomei OP+OEM Front Pipe+TRD Exhaust
ECUTek tuned by HRITuning

Only a problem when at a standstill. Track/Canyon/Highway/Continuous driving has shown no issues, just when I come to a stop, more pronounced with sudden stops.

So basically everything is fine? I just want to Make sure. I can deal with being cautious on breaking so hard just want to make sure I won't cause any damage or have caused any damage

I mean, I'm sick of it, it's so annoying. I've learned the drive accordingly around it. I still need to remove my setrab cooler from the line, because I suspect the fluid may not be getting up to proper viscosity.

They can

if say you do a j turn in a parking lot incorrectly, or if there's an idle air control valve problem, or bad maf. Most of the time it's an engine problem not a trans issue.

Well, now @soulreapersteve , usually it's the engine that stalls ........ automatic transmissions very rarely stall .... and when they do, the inside has turned to mush .........

That's the reason why some call automatic transmissions "slush boxes" ..... because they sometimes turn to mush.

Sorry, ......... it's a real slow day down here in Puyallup .......
