Same issue today.. car stalled while driving. Idk if the led brake lights or brake light switch or there’s a short somewhere but wtf.

Hopefully I am all good. I will stay pay DMV on time.

-bump- - @apexi - I was checking for possible spots for where the oil can be leaking from and my first thought was checking out the oil cooler one since apparently that is common. The oil filter was dry with no fluid on it, I am not sure if that means the gasket is fine or it still could be faulty?

Hmm well they have nothing to do with smog actually. Some other people said they passed because the tech said as long as the CEL is not actually on before/during smog, they will pass.

Dumb question--My car is due for renewal soon and I wanted to know if there are stored codes will this cause me to fail smog? My CEL is OFF and has been for 5-6 days. I am in CA. Thank you.

@apexi thank you for the info and feedback. I can not believe that LED's could be causing this or a bad brake light switch (my brake lights work as they should btw)...so stupid. The OCV issue is fixed, there is no CEL for it nor any stored codes. But I will remove the filters when I get a chance/when it stops raining for a bit.

BUMP- @apexi Stored codes- P0700 & P1718, car runs and drives fine. I drive it slow though even on the freeways. Bought and already got a used TCM. Can anyone, please, chime in and give me some advice? I read that even a loose connection could be causing all this. Oh and if I am not mistaken, is the TCM located driver side firewall? Can anyone tell me what is the best method to get to it? Thanks again all. Appreciate the help!!

Have you checked for possible intake leaks? If not get a can of starter fluid or something similar and spray all around the engine. If you hear it surging, you have a vacuum leak.

I would drain the oil to see if you find any metal fragments. I agree with Sean too, swap the OCV's, drive the car for a little bit and see if the code changes to P0021. Also, as TY said, remove those pesky filters, they do more harm than good. It reminds me I have to remove the turbo one as well as the one behind the timing cover.

Bumping own thread---P0700 and P1718 are now permanent...car has been driving fine. I have not reset the code, after further research it seems that it could be indeed be a faulty TCM or a short somewhere between the TCM and ECU or somewhere else. I purchased a TCM from eBay and hopefully it will be here soon. Will replace it next week and keep yall updated. This may be a stupid question but will the TCM require programming?

So update y'all. Got a mechanic to come look at it. Leak is not that bad but I think the seal inside where the oil filter goes is bad thus causing the leak. Oil is not low but not full either so going to add some oil in. After looking at everything he took off the positive terminal for 5-10 minutes put it back on and it went into drive. Pulled the code of P0700 though. So we are guessing the TCM will need to be replaced.

So I decided to check my oil after a lot of people recommended me to..and good thing I did. See pictures..oil change done about 2 weeks ago with 5W-40 and some people say that it may be too thick and the banjo filter(s) may be causing it to spew out oil. Edit: sorry, do not know why my pictures always seem to upload weird.

Hmm and it is weird that I do not have a CEL...I will look into this, I found used assemblies for around $100. Thanks. What do you recommend I use to clean up the OCV? I plan on cleaning the TB tomorrow so might as well clean up the OCV's. I will try my best to get that filter behind the cover out but I am not sure if my skills would be good enough for that. Oh and I had the code (P0021) beginning of November but it went away by itself after 2 days, which I did find weird. Fingers crossed that cleaning up carbon/debris/dirt off the TB will help.

I will order one after logging but for now I need my car to get back home for break and I will clean the TB tomorrow (if I am not mistaken it is underneath the TMIC?) The battery is under warranty but since it is "good" I have to buy a new one. The good news atleast is that there is no TCU codes. I was able to borrow my friends laptop quickly to check and there were no codes that appeared. I used FreeSSM.

Yes I got the compression dealt with, swapped head with a low mileage one. They said my battery and alternator are good, but the battery is leaking quite a bit. I see autopart stores selling the TPS separately, but did some research and saw you can't replace it on this car..? So confused by that.

I am the one who put the intake on, did not get it tuned yet however. I am using BlueDriver. (https://www.bluedriver.com/) This may be a dumb question..but could a bad battery be causing this? Thanks!

How do I do that? I mean I have a bluedriver connected with data logging. I do have a SPT intake, not sure if maybe that an aftermarket intake could be causing that?

https://legacygt.com/forums/showthread.php/help-please-car-stalls-put-d-275855.html?highlight=please--car+stalls This was my original thread (^^), however this time I have no CEL at all. I cleaned the MAF and replaced the air filter. No luck. Had this issue a year ago too. Sticky throttle body? Sticky TPS? Someone please help me, I am a poor college student with barely any money.

Thanks! Thank you, I bought it from Subaru! I bought the OEM one from Subaru, and I see..but this is closest one to the A/C so I feel like it could help a little.

Thanks a bunch! Random question though, could this cause weird issues with the car?

Hi all, I was wondering if any knows where I can get ground straps? Also, what type of gauge is it (if that matters)? I think my passenger side one that is under the car ripped and I just want to replace it. I have not gone under the car yet but just wanted a little more info before I do. Thanks!

Hmm, I have not experienced anything like this. Could very well be a wiring issue or it could be the TCU. First step I would highly recommend is following these steps: https://legacygt.com/forums/showthread.php/5eat-tcu-reset-w-freessm-202482.html Next step, I would say check the wiring, ground cables, and transmission fluid. If none of those seem to help or work, you would have to take it to a shop and ask them to run a diagnostic test on the TCU for any codes. If it seems to be shifting fine without jerking or bang shifting then it does not seem to be an issue with the transmission IMO.

Weird...I put LED's front and back with the relay and I had no issue. Did you check to make sure it was properly secured into place? Maybe try re-installing it or could be a faulty relay. I trust diode dynamics a lot more than iJDMtoy.

What is going on with your transmission? I have a 5EAT as well.

That is correct. It was not a complete engine swap. Also--the CEL turned off by itself today as I was driving home. I did not reset it or touch the OCV or do an oil change (that is planned for tomorrow).
