Hello, I'm here bc I love your channel. Been a fan for many years. I have a car problem no mechanic in or outside the dealership has been able to solve.
2013 Ford Edge Limited Ecoboost 4 cyl
The car will randomly die while driving or when stopped. If I Rev the engine it will stay on longer but at slow speeds eventually dies. The dealership replaced the purge valve assembly, the master break cylinder(booster whatever its called), they replaced all the hoses bc I could smell fuel sometimes. The car lasted about 2 months then started doing the same thing. When it dies it says oil pressure low, the sensor has been replaced. The CEL throws a code for right bank sensor which was replaced with the purge valve assembly. It's costing me to much money so it stays parked now. What on earth is left that could be doing this?
Does anyone in this world know how to solve this or had to deal with the same thing? I'm defeated and about to give up entirely. It has 80,000 miles on it and won't get another one until I can figure this out or just scrap it for a few bucks.
Anyone out there that can help, please I beg you, I'll try anything at this point. Thank you for your time.

Please post all codes here, thanks.
Well have a mechanic check the real oil pressure with an actual gauge while it's running and if it really does get low oil pressure and unconked out means the engines wearing out inside and the lack of oil pressure forces the computer to shut the engine off. If not that those things are complex electronic monsters and as you found out, even the Ford dealer's really don't know how to work on them. Good luck
The turn signal audible warning is working good because I can hear that really well. Next time you post a video turn off the signal light. We can't hear subtle engine noises with that turn signal noise.
Anyway, I'm just "spitballing" here but it's possible the cam phaser is intermittently staying locked during "engine hot" low rpms. That's going to throw the valve timing off and if the rpms drop low enough you can get an oil pressure code. (and engine stalling at idle or low rpms because the valve timing is off)
It becomes a "chicken or the egg" paradox.
Is low oil pressure messing with vvt solenoid operation or is it something like a timing chain tensioner or a sticky vvt solenoid causing such low rpms that it sets a low oil pressure code?
Don't forget, dirty oil either now or in the past can mess up vvt solenoids so make sure you have clean oil.
Maybe unplug the wiring connectors to the vvt solenoid and see if it still stalls at idle/low rpms.
Sure you'll set a vvt solenoid circuit code but that system is 90% for emission control and maybe 10% performance and it would be interesting to see if you still have the stalling issue.
The codes are no longer showing up. I think it was a P207 02 right bank sensor. The oil pressure lights/codes all gone as well. The only problem left is it randomly shutting off when I'm driving. At random times the rpms will start to flicker as in this video. When this starts, I know I have about 2 minutes to pull over bc it's about to die! Lol. Thank you so so much for responding. I appreciate you and your work! I think the dealership has solved all the codes and issues mentioned with their work other than the main issue of it dying. 🙂
