Engine shut off by itself!
 

First, let me inform everyone that this happened two years ago. Apparently I can't remember if my car was modded at the time. Probably not, but if it was, it was only an injen intake.
Anyways, I remember that two years ago my car suddenly turned off by itself. It was an extremely hot dry Friday when it happened. I had just gotten off of work, and drove home which is basically a 30-40 minute drive due to traffic. I want to say it was in the high 90s considering that I do live in Texas. It was as I was pulling into my drive way that my car shut off by itself. I just turned it back on, drove my car 5ft into the driveway, and shut it off immediately. Has this ever happened to anyone?
I just figured I'd share it with the ft86 community

My experience was with my 2010 Corolla where I had to jump start it due to a bad battery. Drive it down the street and the car dies in the middle of the intersection. No power steering (or any steering in that case), lights, or boosted brakes. I assumed once you jump it and the car is running off the alternator, the battery strength wouldn't matter but I guess it does.

This just happened earlier this week.

It does run off of the alternator until the engine goes to low idle. When the alternator isn't spinning quickly enough to function, the system goes back to discharging the battery. If there's no charge on the battery, everything dies.

OP had some other issue. He could start it right back up so plenty of juice in the battery.

Perhaps climbing hill if your driveway is sloped and the car rolled back a bit and killed engine as precaution?

Nope

Actually, I can't quite remember wether or not I turned it back on. But the car definitely died on me. Maybe it was because these cars idle as low as 500rpm when stock

Was the problem replicated? Could you reproduce the problem?

If not? Ignore it.

If so? It's a problem.

I never tried to replicate the problem, nor did the problem ever reoccur. I basically did ignore it due to the fact that this problem happened two years ago and I'm barely sharing this. Just curious if this happened to anybody else. Just wondering if it's normal.

what?

No, its not normal. And since it happened once, 2 years ago, I really don't think I would even give it another thought!:rolleyes:

I hit a skunk about 2 years ago. It made a mess. Don't remember if I hit another one since. Just thought I would share.

Two years ago I hit a little minivan with an up-armored Toyota Landcruiser. The bull bar actual tore through the side of the minivan into the passenger compartment. Fucker shouldn't have tried to cut across traffic on a muddy street.

Haven't done that since, though.

Did it turn into an oil cooler? Would be a fortuitous turn of event .

lol

So, nobody else experienced this? Odd

Why odd? You said it only happened to you once and that was two years ago so not exactly a chronic problem. There are 1,000 things that could have blipped once and caused it. Cars are complex and just one little thing wrong can shut it down.
Don't even know what made you mention it 2 years after the fact in the first place.

Odd that it only happened to me I guess. I brought it up because I wanted to share to the community what happened, and wanted to know if it happened to anybody else.

Considering you don't know if you have an engine mod or not, I don't find it odd.

Engine stalls like this usually are from a vacuum leak. I'd suspect a poor intake install.

Thanks. I believe there were multiple people having issues with the intake as well

I've had this happen a couple times, but always managed to just start up again.
I also have an Injen short ram intake, so that seems to be the common thread.

Doesn't happen often in normal driving (I'd say it occurs on about 1% of my drives, and only on hot days) but it did occur a few times after my last track day, so it does appear related to heat.

If it's injen then yes there were a lot of people having issues with it. (including my brother)

Never experienced but had issue first few days where the a/c would kick in, i'd be slowing down pressing break and rpms would crawl so low if i let go of the clutch further, it'd prob turn off or if I was on a uphill angle.

Check ur MAF, before I have TRD intake and go to track, when I spinning out, the MAF is broken, dealer said too much air in

Hmm... That is troubling because I did spin out at my last track day....

I think we have same problem, change a MAF, maybe around 300+...

Wow, kids these days.

This is what happened, your battery died. Hot temps in traffic will drain the shit out if batteries. Given that your battery was fairy new it had just enough juice to start. After it cooled down over night, staring up in the cooler morning the alternator did it's job and charged it.

It may be 90*outside but it's well over 130* inside your hood. Heat does weird shit to everything.

A battery will cause a car that is running already to shut down?
Interesting.

Meh - problem hasn't come back.
The car has run like a champ in the week since then.

I'll leave this be.

A competently dead or dying one yes. The ecu gets it's power from the battery. When the ecu doesn't get enough juice, there's not enough power to send spark. So instead of causing a misfire (do to a weak spark) it would just shut down.

Yep, a drained battery that is not being re charged because of a bad generator/alternator or a stuck voltage regulator (back in the day) will cause a gasoline engine to shut down.

Why? Cause the spark plugs can't get any more juice to fire ......:eyebulge:

Of course, the exception is, if the ignition is powered by a magneto. Don’t rely on that, unless you have a hand crank under the seat ……. :D


humfrz ...... :slap: ...... finish your cup of coco and go to bed.

Haha thx guys... That's good to know. Thankfully, my car has had no problems cranking and runs fine except for those very rare instances.
Learn something new everyday on this forum (and sometimes it's useful!)

Issue spawned recently on my drive home. Shut off numerous time but would turn back on w/o a problem. No CEL or other warning lights on the dash.

Found this walkthrough to clean the MAF sensor.

I had recently cleaned my drop in filter. Never thought to clean the sensor.
Drove it in this morning, car didnt sound like it was going to shut off during idle. :bellyroll:

Quick update: Issue has not resurfaced.

Perhaps you just turned it off for no reason? I mean honestly you seem to have forgotten more about this event then you remember so you never know.
