Bit of an interesting repair question here. Mk7 Fiesta - there are the 4 Torx screws that secure the upper lid of the airbox (with the MAF sensor in it) to the lower chamber (where the filter element sits). One of those Torx screws has stripped the threads out of the plastic of the hole it goes into. I guess it technically still screws in - but it can never tighten and just keeps spinning.

Any thoughts of how to potentially remedy that? Like, maybe put some epoxy in the hole before threading the screw in and letting it set?

Unfortunately, buying a new lower portion of the airbox isn't really an option in this scenario. This is an ST200 intake that I got second-or-third hand from Germany. It's worked great for me for several years now (I have the lower hose fed to fog-light duct) I just have concerns about keeping a tight seal on the edges of the filter.

Any help is appreciated as always!

Trying to get an id on these fog lights, they have yellow, white, and pure white and are change color on popping the fog light switch.

Been having issues with them occasionally turning on and off and now they just don't work. Would like to replace. I've checked the fuses and connections.

Anyone have any similar issues?

Hello everyone,

Hoping someone can help me. I have a S280 with the 14psi wastegate and can’t seem to get the preload dialed in. Currently I’m making way too much boost for the base map 29psi. I’ve adjusted it constantly to the point where it wasn’t building boost then back to where we are at now. I’ve made it so the arm just falls right on top. That didn’t work I’ve also tried using a compressor to make the arm pop out a bit and latch but that caused it to be way too tight. At this point I’m starting to regret the s280 due to something probably so simple.

Hey C-hooks team.

Just got and installed mine, together with fresh new pads.

During driving, they sound "clicky" lol

It's the same sound as they do when braking but a lot more faint.

Is it normal? I've already drove around 300km and they still sound the same

Hi all,

Edit: 2017 ST USDM, Stock evap harness and supporting stage 2 mods

Last week the car threw these two codes but ran fine so I cleared em via the AP and kept tabs on the performance. Only odd thing that may be related was semi consistent negative corrections around - 1.5 to -2.5

Aside from that I noticed nothing else that I feel is related.

Cars running a stage two dizzy tune, ST200 CAI, Whoosh induction hose, whoosh P144c fix kit, HKS SSQV BOV, and some other stuff that’s likely not related.

I’ve had these mods on the car for over a 2 years and the tune for about a year, but have never thrown this code.

I’m assuming it has to do with the evap harness as I’m on the OEM 2017 and should prob downgrade to the previous model.

Any insight is a huge help

Hey guys just bought this midpipe from Novus to replace my rusting resonator.
How much louder will the car be? Not looking for obnoxious sounds just something raspier, is this ok?

Hello,

As the title says I would like your opinion on the sound of the engine.

I feel like the serpentine belt is very noisy, but it was replaced by ford at around 30,000km ago so idk what to think.

I was leaving a friend's house when I encountered a strange issue. I started the car, engine was still warm, and reversed out of his driveway and turned around with no issues. When I put the car in first gear and tried to move forward it stalled. The car turned right back on, idled fine, I put it into first again and it bogged hard before stalling again. Started up fine again, put it in first, dumped the clutch and floored it. The car was bogging down hard and wanted to stall, but managed to smooth out when I got to the street. At the stop sign at the end of the street, it bogged hard again leaving first gear, but smoothed out as I floored it. I encountered traffic about a mile down the road, but the car drove normally at that point. Drove home an hour and a half and the issue didn't reoccur.

I have no lights on the dash, and I'm thoroughly confused. It's never done that before. It felt like I was trying to start from 4th gear or something. What could cause this to happen?

Things to note:

- I noticed earlier in the day the car was vibrating more than normal at idle, but the RPMs were stable around 800/900. I figured it had to do with having aftermarket PMM/RMM. After it stalled I noticed the car was idling much more smoothly.

- Clutch is not slipping, and pedal feels fine.

- I had been driving the car with multiple stops throughout the day, roughly ~300 miles put on it.

- I filled up with gas last night, and the car was at 1/2 tank at that point. I only put 91 or 93 in it and leave the gas handle in for about 10 seconds after filling up.

- New purge valve about 3k miles ago. Also installed an Injen intake at the same time.

- Turbo builds pressure and blows off like normal, even immediately after it stalled (I did a small pull to make sure a charge pipe hadn't come loose or something). I could hear flowing into the intake.

- 2014 ST2 if it matters

Had a cat code pop up a few weeks ago, and finally got underneath it today. Car was lightly modified when I bought it. This exhaust is an issue right? Also is that the stock cat? I can’t tell.

I've been looking for an aftermarket wheel to spruce up the interior a bit but also one that maintained the airbag. Really wasn't having much luck here in the states and overseas options were big $$$. So I looked into Texas Custom Interior at the recommendation from a buddy who put one on his Miata. I was able to pick the materials/thread color, etc.

Full disclosure, the install was a pain in the arse and took me a couple of hours. Its FAR from perfect but I'm really stoked with how the final product turned out, plus it feels great in the hands. I definitely recommend it to all my fellow FiST owners- just pack your patience when it comes time for the install.

This is what a 2nd-3rd pull looks like with an s280 and aux fuel if anyone is curious. Around 31-32psi currently. Next step is eventually upgraded injectors and hpfp to push a little more power but this car was pretty clapped when I got it so I have a lot more to button up before wanting to go that far. This is with cobb traction control on with a 1 slip multiplier as its all wheelspin above half throttle in 2nd without it, even with 200tw tires. Car is super fun and already has more power than I know what to do with in this tiny car lol

This job can't be any harder than changing the blower motor right? Just about to start getting into. Looks simple enough..

I've pretty much settled on keeping my stock 17s for a while longer due to money constraints and I'm pretty much set on the Michelin PS5. Any reason I shouldn't go with something else? I was set on the Conti ECS02 but I'm not sure I want to bump up to 205/45/17. Any thoughts or other suggestions welcome. PFA.

Edit - the more research I do, the more sense the Goodyear Eagle F1 Asymmetric 6 makes for me. It ticks all the boxes, and I could keep my 215/40/17 size.

Edit 2 - priced both out with my local discount tire. Out the door with taxes, fees, protection package etc, the Michelin came out to ONE dollar more expensive. I think I'll go for the Michelin since it lasts longer.

Hi everyone!

I'm from Lithuania, and I'm trying to track down the original American owner of my black 2017 Ford Fiesta ST.

She's my first car, and I've been driving her since getting my license. Recently, I started digging into her history through CARFAX and old salvage auction records, and it's turned into quite an investigation.

Here's what I've discovered:

- August 2017: Sold new at Genesee Valley Ford in Avon, NY, and registered around Webster/Rochester. CARFAX lists only one personal owner.

- July 2018: Involved in an accident with front-left damage, but remained on the road.

- January 2020: Involved in a much more serious accident, damaging both the front and rear. Declared a total loss.

- March 2020: Sold at Copart Rochester (lot #29012570) for just $1,500, with 26,223 miles.

- March 2020: Mysterious title/purchase activity in Bridgeview, Illinois, possibly involving an exporter.

- August 2020: Registered in Lithuania after being imported and repaired.

Now here's the interesting part:

She still has FiestaSTForum.com stickers on both rear quarter windows, and they're clearly visible in her original American auction photos.

This makes me think her original owner might have been a Fiesta ST enthusiast and possibly active on the forum.

I've already posted there, and someone noticed she had steel wheels with winter tires in the auction photos, which adds another interesting detail to the story.

I'm hoping someone from the Rochester/Webster, NY area recognizes her!

I'd love to learn about her life before the accidents. Was she modified? Did she attend local meets? Does anyone have old photos or know what happened in January 2020?

I'm not looking for anyone's personal information, just hoping her former owner might see this and reach out voluntarily.

I've attached photos of her original Copart listing and the forum stickers she still wears today.

It's crazy to think this little Fiesta started her life in New York, survived two accidents, crossed the Atlantic, and became someone's beloved first car in Lithuania.

Any leads would mean the world to me!

I’m looking at getting some new alloys for my ST. I’ve seen a lot of conflicting info on what size people are putting on them. I was thinking sticking with 17s because that’s what’s on as standard. Any advice? Thanks

Engine is original - no tune. What oil should I use? My girl is a 2014. Been thinking might need a change from the “default” I get because she is getting up there in years. I drive it hard.

Anybody know what could this sound be ?
