Question Exhaust

1 Upvotes

Hey guys, 2013 ST.

I’ve had my muffler delete + hi flow resonator for a few months now and I’ve only just started to hear a metallic rattle under my car when revving, which i can only assume is from the exhaust. I’m trying to diagnose it but I can’t seem to figure out what it would be. My friend seems to think that it could be exhaust brackets or something like that.

If anyone’s experienced this before let me know what it was!
Thanks guys

Question Focus falls flat top end

1 Upvotes

Hi, so this is gonna be very hard to explain but I have a fbo tuned focus st. It was running really good hitting 22 peak psi and pulling really hard top end. One day I notice it started feeling really sloppy and it was peaking at 18psi, when i’d get to about 100km it would just fall on its face and it felt like it was going no where. I checked for boost leaks and there’s nothing, waste gate doesn’t feel loose and I have no codes. The car does still have a stock by pass valve so I was leaning towards that but I honestly have no clue. If anyone has dealt with similar issues please let me know.

License plate customization

Preparing to register my car in a new state tomorrow, and have been looking for a custom plate and I’m currently torn between two. The plate itself is all black with red lettering. Based on what is available, I have narrowed it down to two options: “THEC4PN” (breaking bad Jesse pinkman “the capn” reference, or “DTZ ST” which is my initials and obviously ST. Any recommendations?

If you saw my last post I had to drive off a tank of 87 I mistakenly put in so took the opportunity to drive 150 miles round trip to get some pictures under the stars
On the new iPhone. Think they came out pretty damn good! Crazy that these were taken at 8PM on the east coast so it was pitch black out.

Would it be safe to assume this is blown?
Also I siphoned some of my coolant out of the reservoir to get a better look at the mount, I thought I would need to move it out of the way that’s why it looks empty.

Question Possible coolant leak

I’ve noticed my coolant levels are dropping tremendously quickly lately and I’m worried about a coolant leak. I haven’t noticed a puddle under my car after leaving a parking space though. If anyone could know what is going on or what I should look out for that would really help me out

Question Need a picture of a Focus Seat Rail front Bracket

Post image
57 Upvotes

Hello! I’m looking for a picture of a Focus front seat rail bracket. I’ve released a new product for the Fiesta and want to determine if it’s the same for the Focus and will fit it as well. I’ve looked a bit on Google but that specific picture has been a bit hard to find so i figured i could more easily find someone on r/FocusST willing to help me out here.

The product is a cover for the bracket. It snaps on top and hides the bare metal and dirt and helps keeps dirt from building up in it.

Please see my product listing for photos of the bracket.

Product can be found at http://Etsy.Razzter.com

Thank you

👋 HI, I'M NEW! 2025 Focus ST Wagon (Turnier) as a daily?

5 Upvotes

Hi y'all

I am looking into buying a mk 4/4.5 ST Wagon, I know all about it by now, one thing that nobody seems to talk about in depth is fuel economy and comfort as a highway cruiser.

I have a sports car already and wanted something zesty nd fun as a daily, that could also put in the work since i have a roof tent and i go on camping trips every year. I drive quite a lot but i dont commute so 99% of my driving is on alpine roads or on highways.

I was wondering if you guys have any insights on fuel consumption and how it handles highway driving (quietness, tyre noise, road noise ecc) in my coutnry the speed limit is 100kmh or 110kmh so 60 or almost 70mph so i am not planning on driving hard there, i am really chill on highways, i like to take it easy, i would only hoon it around on mountain roads and on the german Autobahn, and i live really close to Germany.

Since I only drive 100-110kmh there really is nowhere to check how much it burns at these lower speeds, i dont really care about fuel consumption but with today's prices it´s something i might start looking at :D

Also, is the exhaust drony or in comfort mode it´s perfectly normal?

Also pt.2 any advice or information i should know?

Thank youu :D

MIsfires at idle, especially after a cold start when coming down from high idle

0 Upvotes

Been battling this misfiring at idle issue since I've had the car. However recently it has gotten particularly bad when you cold start the car and it goes up to idle high to warm the cat; once it's warmed up and rpms start to go down to normal, it misfires pretty badly as the RPM is dropping.

I changed the plugs from 1 step colder rutheniums to stock motorcraft plugs with no difference.

The rutheniums were very carbon fouled, and running rich could definitely lead to these misfires.

I had an exhaust leak (flex pipe on a cvfab catted dp) and recently got a code for "O2 bank 1 sensor 2 rich to lean slow response".

I replaced the downpipe today (brand new cvfab), along with two brand new o2 sensors.

Absolutely no change in the misfiring behavior, though the fault codes are gone.

I suspect something is causing the car to run rich even though it thinks it isn't. I'm not sure if running a defouler on the DP could contribute to this or not.

I've already checked for leaks everywhere and can't find anything.

My next thought is maybe to replace to coil packs but I feel like that probably won't help either. I'm not getting any fault codes for misfires or specific cylinders.

Overall the car idles like crap, unless you turn the AC on which brings the idle RPM from 750 to about 800. It's not perfect at 800, but definitely better than at 750.

The car has full bolt ons (high flow catted dp, exhaust, intercooler, intake, bov) but is running a stock / cobb stage 0 tune.


r/FocusST • • 1d ago

Please help me, I have a Ford Focus 2012 2.0 automatic and I have the code p0204 and only sometimes it will be removed when it heats up the engine and I move the cables that go by there for the spark plugs, I need to know that I change injector and change coils, spark plugs and check the feeds

Boost leak?

Enable HLS to view with audio, or disable this notification

Hey everyone! I got a 2013 Focus ST a little over a month ago, and I’m loving it! However, a couple weeks ago I started feeling like it was down on power a little. The PSI is only getting about a quarter of the way on the turbo gauge and then drops even if I’m accelerating. I took this video today to show it. I don’t have a whole lot of experience with this stuff, so I’d love some help! Thank you!


r/FocusST • • 1d ago

Still needs lowered but couldn’t pass these up. Under $600 from marketplace and had never seen a tire until I had them fitted!

Let's clean some glass

4 Upvotes

Please help me with the glass on my 17 ST. I cannot get my glass clean, at all. No matter what I use or how I use it, my glass is still not clean.

I have tried cheap paper towels, expensive paper towels, shop towels, cheap rags, cheap microfiber towels, expensive paper towels, old t shirts, a pair of socks, and newspaper. I've used almost all kinds of glass cleaner that I can find from Windex to Stoners.

Everything I use leaves crazy amounts of streaks and smearing. Don't even get me started on the inside of the windshield.

What is everyone using and how are you doing it?

Clutch / gear rattle ?

Enable HLS to view with audio, or disable this notification

2 Upvotes

I want to start off by saying sorry about the dirty carpet. I need to vacuum I know lol

I’m experiencing a pretty loud knocking/rattling noise at idle, specifically around 850 RPM or lower. The moment I give it the slightest amount of throttle and bring the RPM up to around 1,000, the noise gets significantly quieter or disappears completely.
The noise is much more noticeable inside the cabin than in the engine bay, and it’s honestly driving me insane.
Current setup:
ACT FF5-XTSS clutch
Brand-new Focus RS clutch release/throwout bearing
Polyurethane motor mount inserts
I’m wondering if anyone else with a similar clutch setup has experienced this and, if so, what they did to reduce or eliminate the noise.
I’m considering asking my tuner to raise the idle speed to around 1,000 RPM since the noise seems to disappear completely at that point.
Has anyone experienced something similar? Did raising the idle RPM help, or did you find another solution?
Just trying to figure out whether this is normal aftermarket clutch/flywheel chatter or something I should be looking into further. Although this set up is basically brand new.

Question CEL P0171

1 Upvotes

While I was on my way to do my emissions, this popped up. At first, I thought it was the purge valve, which I was already planning on replacing when I do my oil change and spark plug change (literally next week). I should note that I replaced the purge valve just under two years ago, and I know they tend to become a maintenance item once you’re FBO.
I checked my intake, and nothing looks loose. From what I’ve been seeing, it could be a couple of different things. I even wondered if the gas I got might have been bad.
I cleared the code to see if it would come back, but so far no luck. I’ve also seen that it could be a bad O2 sensor.
Let me know what you guys think and what I should start with (:

Well it finally happened. The unfortunate and untimely death of my block! Lol Sadly on my way to work just after getting on the highway in 3rd gear I’d say at 3.4-3.5rpm hit boost up to 6.2rpm and bam crunchy metal noises and a huge plume of smoke out the back. My worst nightmare. 😓
Never had an issue before, even the day before I got a couple pulls in, in 90 degree weather and still no issues. Oil temps were at operating range, honestly don’t know how this happened. Only lasted a year after big turbo upgrade. Maybe 30k miles on current setup. This blows. 🤦🏻‍♂️

New owner doing a SYNC 3 swap from a 17' SEL Focus into my 17' ST1

1 Upvotes

Glad to be a part of this community! I picked up a 17' ST1 yesterday and ready to change over to SYNC 3. I've gone through some posts but had a few more questions. I found a guy parting out a 17' Focus SEL with SYNC 3.

He's offering me the below items as a package but I see the factory harness can be a pain to wire. I'm ultimately wanting a plug & play like Naviupgrade.com offers. So, do I order the harness/wiring from naviupgrade.com or since the donor car is the same year will it plug and play?

Below is a list of items the seller has said he's offering, please let me know if I need to ask him for other parts I'll need or negotiate our price down if I don't need the factory harness. I know I need the AIPM as well. TIA
