So the the first time that my car engine turned off by itself was when I was reversing out of my drive way (about 8 months ago). Today, I was on my way home from the store, after turning on the car, the RPM stumbled, goes to zero, and the engine shuts off. I turned it back on and it was fine. The car starts up normal when it's cold, but when it's already warmed up, the RPM stumbles.

I just pulled some codes off it just now.

P0174
P0171
P0001 (this is new to me)
P0003 (this is new to me)
C0300 (this is new to me)
P0306 (this always come back when I clear the code)
P0303 (this always come back when I clear the code)

I'm not sure why there's misfire, but I had all my spark plugs changed 15k miles ago, and all my ignition coils 5k miles ago.

Has this happened to anyone?

Has happened to my dads car. Has not shut all the way off, buyt close

Does anyone know if valve cover gasket leak can cause this? I think my VCG may be leaking.

Check if all your valve cover bolts are there they tend to brake. Look lower down into the motor to see if u have leaks. I just did my gasket yesterday took 3ish hours but now I'm back and running better than ever if there's a leak it might fix your problem then again if ur leaking oil u should replace your gasket anyways

1st two codes are fuel mixture faults, 3rd and 4th codes are fuel related, bottom two codes are for misfires cylinder 6 and 3. Possible injector failure if you don't have any air leaks.

I had the same thing happen to me in reverse also, about an year ago.
Now I had changed my plugs and coils also and had a walnut blast fine about 14k ago.
And yes I had a miss fire code on one cyln only.

So instead of changing out injectors, tried something cheap .....and 1 year later still no issues.
Not saying my problem is like your problem but worth it if it works.

Try fuel injector cleaners.
And if youv have not got a walnut blast yet, get it done.

Fuel injectors of choice on this forum are:
1 - techron concentrate ( not the one from costco)
2 - BG44k

I ran 2 cans in 2 tanks back to back, one after the other.
Then using USB to obdii cable and bmwloger - reset all adaptations.

I had it walnut blast 15k miles ago. I use the techron fuel cleaning every 5k.

[BashShah]

Try a full adaptation reset.
I used bmwlogger with USB to obdii cable.
