Just this morning to work, I noticed the Flex was crawling between 90 to 100. Thought it may have been just a fluke. Played around on the drive home and the torque is still there at the bottom end for the most part, but then the pull weakens as the rpms go up, then pulls harder again once it shifts. Old school me says fuel filter, but after looking it up online, there is no fuel filter to change?
33k miles
Never modified or tuned
no engine light.
no rough idle or studdering.
I use 93 octane from the same station every time.
Any ideas? It's under warranty still, but just hoping there's something I can check myself before handing the stealership 100 bucks.
I would like to see you tell the stealership you are having this issue at 90-100 mph LOL.
When were plugs and fluids last serviced? Belts look ok? IAT snd IAT2? I would start there. Might be cats, but doesn't seem so. If you have climate control on, may not be putting out enough voltage/amps. If all else fails, check that fuses are firmly seated in the engine comp fuse box and try a KAM reset.
Oil changed about 1500 miles ago. Doubt the plugs have been touched. Unless they check the plugs when Ford does the Ford certified thing, which was done at 21k miles. I'll try a KAM reset. Ty Hopefully not cats. Found out the hard way Ford warranty does not cover exhaust with the taurus.

Ford CPO is a joke IMHO, BUT it gives you access to the best and longest warranty offered by Ford.

Very dependent on tech and dealership...
I really don't think so ... the payoff isn't there for them to do an in-depth inspection I guess? Do they really put their best and most experienced tech on the job for CPO? Does that tech have experience specific to that car/powertrain?

My guess is a big No. I looked at a local "certified" car and noticed one of the tires didn't match, looked closer and a spot on the wheel had a different look to the finish. Huh, the dang wheel is bent. Start looking over the front end on that side real good and sure enough, a little overspray and tape marks. This car has been in a wreck Buddy. He couldn't even begin to build a argument, quite obviously.

My car was a CPO and had new tires but they were the cheapest damn tires possible on it. I talked to the dealership about putting the correct OEM ones on and they told me to pound sand. Two of my SHO wheels were also curb rashed. Don't hold your breath that CPO stuff is awesome. It's better than nothing but don't blindly go in thinking it's "as new".
What it is it's a biz and it's dirty , you'll get rich but life expectancy is about thirty
Now what you want me to do? Lol lol lol
This is not related to the ecoboost platform but most recently purchased an 03 G35 and noticed the other day it still had the original oem tires which were dated late 2002 exactly when the vehicle was built based on the date on the tires.
This was indeed a one owner corporate vehicle which then purchased it as a pre-owned certified vehicle which means crap!!! Its simply the luck of the draw IMO!
Now Back to the Topic on hand posted by the OP. TIA. Z
Update: i did not do a KAM reset. Have not had time this week. Also I think I left my Bluetooth scanner in the Taurus when i traded it in. So I get to go purchase another one of those...
I managed to run the entire tank and refueled more 93 octane but from a different station. Still acting funny. Also there's a squeal at the shifts at 3/4 throttle, but not full throttle. I honestly could not tell if it was the tires chirping or a belt squeal. Anyway it is going in the shop. The Flex has also developed a funny noise in the steering. That popping sound you hear when you turn the wheels on gravel? Just like that, yet I'm on pavement.
Thank you guys for the suggestions. I'll just let the techs figure it out. It's amazing how much available time you lose to fix your own car once you have a baby......
So the dealership called. The Flex is overboosting and they can't figure out why. Still no engine light. Their scanner is reading 20PSI with spikes of 29PSI and the fuel can't keep up. So they thought this Flex may be tuned so they checked and found that it is in fact stock so they are stumped so far. Now it is accelerating like a bat out of hell from stop lights at 20% applied throttle. It's also surging at 50% throttle, boost going all over the place. Looks like it will be at the shop a few more days...
Turbos, BOVs and the hoses atop the manifold would be the obvious things to check in an overboost situation. They have verified all those?
I imagine they will first thing in the morning. I'm guessing a BOV. They also ordered a new door hinge. They think that is causing the driver door open alarm going off once a week going down the road. They can't seem to get the steering to make the noise I hear.

Well that would explain it. The taurus had over 80k when the cat went out. But they covered the bad injector that caused the cat to go bad.
They called again today. The mechanic is claiming a bad EGR tube is causing it. They will try to replace it today before I'm off work.
EGR tube? Would love to know where that is on these engines!

Funny I was thinking the same...EGR generally is handled via cam timing strategies now...quin ask them where that tube is because there is not on that goes from the exhaust to intake anymore
I will when I pick it up tomorrow afternoon.
They replaced it and claims it's running great now. They are just waiting on the door hinge to come in to fix the driver door ajar alarm.
This is confusing... So the mechanic calls it a EGR tube. The front desk lady said it's a wastegate solenoid and the manager called it an emissions tube and claims Ford calls it a EGR tube.
Bill: Performed EEC found code P0234, Performed PPT HN1-Y, HN2-Y visual concern, vacuum supply - vacuum hose swelled out
Correction/action taken
Removed and replaced hose, cleared code and retested to verify correction

Referenced as a vacuum tube, I suppose it works as a pseudo EGR tube :D $4 part causing all these headaches? SMH.
SO essentially its only a wategate hose!
The hose swelled out due to Ford NOT installing a hose clamp from the factory!!! Z
Must have been it, cuz it runs great again.
They fixed it right, then, and that's what matters. Enjoy!
2013 Fusion SE 2.0L Code P0234 Overboost condition.
The solution for my vehicle was a wastegate solenoid assembly (CJ5Z-9K378-B) which includes replacement hoses and the clamps.
NOTE DO NOT BUY just the Solenoid Ford part (CJ5Z-9K378-A) which is $20 cheaper. While they look almost exactly the same, the electric connector is different and it will not fit. How do I know this? I am insanely cheap. This time my frugal nature cost me an additional trip to the parts store for an exchange.
Learn from my error. You're welcome!
45 min hour install. 20 of that was just finding the location of the part as I did not have a manual. :P
Let the car cool completely.
Ramp or jack the vehicle.
Remove the debris shield.
From underneath the vehicle look for the part on the back of the engine, passenger side, near the turbocharger.
Remove the electrical connector, three hoses/clamps.
The part is mounted on a small bracket with a detent to keep it in place. Wiggle it back and forth to get it off the bracket.
Reverse the process to install the replacement.
I have seen people quote $300 for diag and installation of this part. This was not at all a difficult job at all. Good place to start.
I guess its a personal preference but in the OP case there was
no need to replace the whole assembly and instead you only need to replace the 1/4 wastegate hose which is a simple plug & play install located on TOP of the manifold. Z
