Fiesta ST150 Idle issue fix (Split PCV hose)
Вставка
- Опубліковано 21 сер 2024
- Fixing the idle issue! In this video I've finally fixed the issue which was causing my ST to have a sticky idle!
We tried a few things before this (cleaning the throttle body & changing the air intake hoses) but the issue was actually to do with a split in the PCV hose behind the intake manifold.
This video is what I did to actually fix this issue, and can be used as a guide along side Craigs video of how to take off the inlet manifold, big thanks to Craig for the inlet guide:
• How to: Remove intake ...
Hope this helps anyone with similar issues!
Thanks to everyone that helped by suggesting that this was the issue! you where all right and I owe you all a pint!

I like the way you show your mistakes. It's an excellent learning tool for us viewers. And it shows you have no ego.
No point in hiding the mistakes away! Its always useful to see them to see what you can avoid :)
This video sorted me right out. Had the same issue and was the hose aswell! Gone from 30 mpg to close to 40! Cheers pal 👌👍
Fantastic video, helped a lot. Definitely take your time, especially when putting the bolts back in!
Used this to do mine today. Took me only 2hrs from start to finish with just the basic tools. The masking tape on the bolts stopped any bolts dropping. Cheers!
Glad you got it done!
Great video and thank you, I had the exact same problem and changed out the hose this weekend (March 2022) following your detailed tutorial (I'd never have found the mainfold bolt through the triangle window :)). Intrestingly when I first gained sight of the hose it did appear to be split along the length of the hose, however once I'd managed to remove the inlet manifold with hose intact the outer hose had split and the inner had lost its rigidity and collapsed so I guess when using the car the vacuum would seal this hose and unseal depending on engine air demand essentially sending the ECU crackers! When I first started the car back up for a couple of minutes it really struggled to not stall itself however once warmed up and a quick 10 minute drive around the village the engine was purring. As a note I changed the valve too (simply because getting in this assembly like Jay says isn't a 20 minute job), the clip holding the valve did test my patience :)) however the origional valve was clear. Thanks you again.
Your video was very useful, I had exactly the same issue with my ‘56 ST. Replaced the tube and valve today and now it runs perfectly. The tube was split the same as yours, which I was very pleased to see once I’d stripped it down. The bolt positions you hilited was very useful an I agree that number 1 was the most awkward to get the socket on to. I used a telescopic magnet for removing the hard to get to bolts and also for putting them back - an Essential piece of kit.
Thanks for your video, it was most helpful.
Just wanna say a massive thanks for you're video mate. Changed my pcv hose and valve today due to idle sticking at 3k rpm for a few seconds after coming off throttle. Found a big split in the old hose. Without you're vid it would of been such a pig!
Steve Leggett wicked, glad you got it done!
How long did it take you in the end?
Took me about 4 hours in the end. An hour of that was spent trying to get a bolt I dropped out between the belt and pulley on the left side of the engine :D
Steve Leggett ahaha I had a good while hunting for bolts dropped in the engine bay!
Enjoy the better MPG now too!
@@jaymono6498 hopefully although I put a 60mm throttle body on as I thought that was the idle issue so not sure how much that will effect mpg
Great video, only thing I can add is renew your inlet manifold gaskets, these are four green rubber gaskets on manifold, if you don't know age of thermostat, whip that out and pop a new one in, it's on the left under manifold and awkward to access with manifold in situ, that water hose running under manifold goes straight to it, also, while you have throttle body off and you haven't cleaned it lately, give that a clean with brake cleaner as well👍
Some good advice, thanks! :)
A small niobium magnet inside the socket works a treat for keeping nuts and bolts from falling out when you’re trying to position them
Great video 👍 can't believe how clean the inlet valves are ... Miles better than direct injection engines
I just did this today, took about 6h haha but taking my time and doing it correctly was worth it. Now it runs like clockwork, thank you for the help with finding the problem, my car was revving towards 3k and it was horrible at a cross walk or in traffic now its all good, thx :)
My hose was split on both sides all the way haha why did ford put in a worse hose than my garden hose haha, just to squeeze moneeeeyy
I know you’ve already done it mate but a little trick I try is to stretch a latex glove just over the socket opening then I place the bolt in it and it holds onto it, keep up the vids gives my a good idea on what I’ll be doing to my fiesta when I get one
Thats a good shout, I'll be sure to use that one if I end up trying to get bolts in weird places again!
Thanks for the support
Hey Jay,
After some years and my PVC has gone, lucky enough trying to think why it's was wrong back in the day and it was this silly hose. If we knew people state side have had this problems from 2008.
Thus I don't know how you drove it like that for a year, it feels so wrong. But then again I drove for yrs with no thermostat and never had much heat in the winter. As I thought k&n was making. Me not reach temp.
From getting a nice hose to then seeing a caterham plenum. I think it's upgrade time, hope you're doing well!
Mines the same nice split in the pipe and your vids been really helpful. But what a pain of a job to get out
Jay, thanx for this video my fiesta's been parked for three months and recently just pulled out the PCV Hose 2days ago cause i noticed a split on it, i haven't replaced it yet cause I really cant find it anywhere but after seeing this i'm definite the problem lies with the PCV Hose
Sibabale Mbonyana hope you get it all sorted soon!
Airtec oil breather kit and pcv baffle plate is the way to go, no more rubbish going back into the inlet only clean air 👍
deffo the best way to go!
OMG thanks for the video ! my car also idles like yours did but not quite as bad , im surprised your still only getting 30.5 mpg after the fix as im getting around 31.5 mpg with the idle issue but mine is total stock but thanks again for the video i'll definetly check it out....
Neil Everett mine MOG sits between 32 - 34 depending on how heavy footed I am
Good luck getting yours changed when you get around to it!
@@jaymono6498 great video mate cant thank you enough been scratching my head for age's i knew air was getting in but cant find where lol massive thanks and keep up the good work :-)
A LOT OF WORK BUT WORTH IT. I AM GOING TO DO MINE IN A COUPLE OF WEEKS JUST ORDERED THE NOSE AND VALVE FROM EBAY😁
Good luck, its not as hard as you think!
Thanks for the video. I think I have issue. Thinking about doing it myself, but its seems to be a bit of work. Nice Fiesta. But fix your stearing wheel: Its on the wrong side of the car.
Great video Jay, I have an ST which is almost identical to yours hahaa. Keep up the great video's 👍🏽
Nice, you'll have to hit me up with your instagram if you've got and photos of your ST
Nice job mate, I'm glad you could finally sort it out, now onto some mods 😜 and keep up the good stuff
Got some mods planned, can finally start putting some power through it ;)
Hey man, I love your videos and you helped me buy my MK6. It does have this issue though apart from mine stalls out if the engine isn’t warm enough and it vibrates like mad!
Where did you get the valve part from? I have the pipe but cannot find the other part anywhere
Was your car smoking from the exhaust more than usual before hand ?
Nice!
Did you have more problems like P0171 error or fuel consumption? I have this two problems on my ST and i think i have an air entry with any hoose. Plugs are okay, inyectores, pump...
Thanks for the video!
Great video. You explained everything very well, it helped me out a lot. Thank u
great vid bro just done a service on myn didn’t notice before but ive got the same problem stickin revs , yeah but id say my favourite route would be hole slam pannel off pritty much front off is far easea but more work hate tight fiddly gaps
fix or repair daily ford st/oc midlands yeah probably a bit easier taking the front off, I’ve always had problems trying to realign bumpers and stuff so didn’t wanna mess that up!
JayMono yeah realignment is a pain 🤣
Great video mate just replaced mine. 1 issue. With the throttle body removed. Just below the TB mounting theres a sensor with 2 very small breather hoses coming off it. Im assuming this is an idle air control valve but can anyone shed light on it?? Bottom plastic pipe has snapped off it
Mate ace got the same problem you got a link for pcv valve bud cheers 👍🏻
Brilliant video, I have the exact same problem. I ignored it for ages and it's now got to the point where the engine is misifiring really badly and I cannot drive it. I was driving home and it just stopped, thre was no power and engine failure came up on the dash. I don't know if i now need a complete new engine or if a new hose would fix the problem...
Did u fix?
Thanks for the video. I have the same issue on mine. It's a shame you need to take the manifold off to change it.
Yeah its a big job for something that on other cars takes about 2 minutes!
When I get to do a full clean of the engine bay as one of my next videos after its clean I would love some nice silicone piping
Great video 👍 did this split make a whistling sound at idle and gearing down?
Glad you did it ;-) Also it may have cure flat spots and get back some horses. did it?
It definitely feels a bit more linear in its power progression, it feels like a different car to drive!
As for BHP hopefully, I'm got some plans to find out the BHP figure after a few mods!
Hello Jay, i was wondering which other cars have the same type of pcv hose since i cannot get the same as yours in my country. Thanks for the video.
Almost certain you posted something like this on the STOC forum. Keep these up though mate, no one else posts 150 vids
Wasn't me on the forum! I'll keep getting the ST videos out - got a few plans of mods which will help other people do the common mods to get more power out of these engines!
Make sure you show them the mod where you put a sticker on the rocker cover to cover up a scratch. I must have gained 10bhp minimum from that.
Sacred ahaha stickers are at least 20 BHP each!
@jaymono ezi mate I sorted the car with the new pcv valve its a night and day diffrence I've got mu pops and bangs back n car feels abit pokier bastard of a job though don't wanna be doing it again!!
it is a bit of a fiddly job! Glad you got it done and your cars working properly. How long did it take you to do?
Cheers! Though I still cant understand why Brits use imperial for speed/distance!?!? Metric for life!!!
I'm yet to figure out the MPG:KML conversion but am I right saying that 17-18mpg is high let alone 23mpg+?
Obviously we're not aiming for best economy for eg...
Here but in Australia I just filled up (Paid $2 p/L, Highest p/L amount I've paid usually sits around 1.70 p/L) and the full tank estimates a range of 460km but it'll probably end up around 420kms on empty.
Essentially I get about 10:10 (Kms:L) unless I use the freeway a lot.
Or Im completely wrong?... Its probably the latter :)
Anywho, Enjoy driving your ST150 in proper cold weather!, they weren't built for the Australian summer thats for sure!
Did you not replace the inlet manifold gaskets?
Hi Jay. Can you tell me the part number of that new valve you used in combination with the new PCV hose? Did you need to a replace new gasket/seal between the intake manifold and block?
I would also like to know since mine has cracked
Good vid mate Im doing this job this week but I will be taking bumper and slam panal off its alot easier lol
Matt Newcomb you’ll find it a lot easier! Let me know you you’ll get on!
@@jaymono6498 was going to do thermostat aswell lol so will need to drain coolant so misewell take rad off get access that way 👍🏼
@@matt-it4nl will be so much easier to get both them done without the bumper on!
Great video love this. My cars suffering with the same issue and has stalled a couple times when cold, so looking to change mine. Do you know the part number of the valve as cannot seem to find one anywhere😣 regards
ford.7zap.com/en/car/
I just looked at mine it looks alot harder due to having a cosworth inlet plenum.
Today my st150 when I started it the revs shot up to 4k when my foot wasn't on the throttle. I started the engine in 1st gear with the clutch dipped so I could try and drive home and it went into limp mode giving an EAC FAIL code on the dash. Does this sound like a PCV issue?
What faults code did you have, or did you just assume the pipe had split?
I changed my pcv hose and now instead of the revs holding at 2k rpm when I dip the clutch, now the revs go too low and it stalls. Any advice?
Ugh I'm not looking forward to this job. Did you get any stuttering when trying to accelerate from low revs?
SHARK MEDIA yeah, not a lot but it definitely stuttered a bit.
As annoying of a job it is I’d recommend getting it done, car idles so much better and got like 6MPG Extra so saving pennies!
@@jaymono6498 got the part now and some time off so definitely Will.
I can't believe they didn't include jubilee clips like the eBay photo shows.
SHARK MEDIA luckily I had spare jubilee clips, but you’re right it’s wrong to advertise them and not supply them!
Good luck getting it changed!
@JayMono thank you for that video, but I have a question does the car make hissing noise before fixing that issue ? because I have some idle but not high ones and I hear hissing sound near the intake.
Mine didn't but I've heard that some peoples ST150 make that sound the. the PCV valve is split :)
Have you replaced the Baffle Plate with the Airtec one?
Damn! How did you managed to put that header out ?
I've spent almost 3hours figuring out how to but were stucked & unsucessful.
Had to take everything in place & postponed the fix
I wasn't aware nor believed that it will go out with front face in place
Vincent Ando the PCV hose actually holds the inlet on, so it needs to be removed to pull the inlet out. I ended up cutting mine as it was so awkward to try to remove.
The fuel rail sits in the way too so I loosened that as well. It certainly took some pulling/weird positioning to get it out once everything was removed
@@jaymono6498 thx for feedback
I didn't realize if pcv hose was the true guitly part but header seemed also stuck by some metal pieces going inside the header (on the right if it when facing the car)
Not sure this bad explaination would speak to you but now that I know it's possible this way I should be able to with patience
Vincent Ando there was some plastic locater parts that stick out each side, but they only guide the inlet into the right location so I dunno if they’d stop it coming out.
Did you manage to get it done in the end?
@@jaymono6498 not had time to do it yet but sure will be ok with tour vids & above advise
Cheers mate
This video is so hopefully 👍
When i start mine from cold, i tap the accelerator and the revs go up but then dip down below where it started and almost stalls. Cleaned TB. Any other ideas? Only happens on cold startup. Thanks
A lot of people have this problem with a dodgy idle when cold. Have you checked the PCV for any splits? I know these cars aren't the best from a cold start, some people have mentioned about a ECU update which can also fix/help idling issues. That was what I was going to look into next but mine was a split hose so I just changed that :)
@@jaymono6498 Thanks Jay, is it possible to see the condition or take a picture of the PCV hose without having to remove the inlet etc? Looks like a ball ache!
@@TapDancingOnYoFace I'm not too sure, I've heard people trying a paper test for a blocked PCV valve
(Remove the cap from the oil filler hole on the valve cover and place a stiff piece of paper over the opening. If your PCV valve is working properly, the paper should be sucked against the hole within seconds)
But I'm unsure if this will work with a split hose! You might be able to see a little bit of the hose but the split might not be on the side you're looking at.
You could look into the T map sensor in the front of the inlet manifold sort of below the throttle body, two wires going in and a torx bolt holding it in remove it and gently clean up any oil & carbon off it using a spray like you probably used on the throttle body Craig DIY tells you all about it it's a thermistor and sends a signal to the ecu for air density/ temperature changes, although I think this sort of age Fiesta 2.0 duratec it's a common problem, I fitted a ST150 inlet manifold on to my focus 2.0 duratec straight swap and fitted the same roose motorsport hose & new PCV valve as a precaution & to remove the swirl flaps, of course there's a little more room to work under the bonnet on a focus
@@jaymono6498 For anyone interested. I took my inlet off last night, and my PCV hose was totally fucked, split all the way up and wide open. I replaced the valve with a new one, blanked off the inlet and fitter an airtech oil cooler/catch can kit. All my issues are fixed.
Thanks!
Jay I have what I feel, the same problem you had. Only difference is that since the problem occurred, I hear a whining sound as well except under acceleration. Any insight?
Fahad M are you definitely sure it’s a split PCV hose? Sometime when’s there’s a split in a air line or vacuum line is can cause a whistle sounds, I’d say change the Hose if you’re pretty sure it’s that and if it’s still there check your intake hoses and vacuum lines ect!
Hopefully it’s just the PCV hose and it will go away when that’s changed
JayMono will do! Thank you for the help 😅
Hi jay thanks for the video, think mines split too, maybe gaping. I'm having trouble finding the valve you replaced, could you direct me to where you got it from cheers rj
I got the valve direct from forepartsuk.com, and the hose from Roose Motorsports eBay page
@@jaymono6498 oh yeah I used them before. Thanks jay I'll take a look. Seems fordpartsuk has shutdown : ( took a while for ford to find the part it's described as a connector and is part number f1251743 (£14.32) For anyone else looking.
Just an update there was a 40mm split! What a transformation, drives much better, stable idle, no stupid rev hangin. Would not have thought of this issue myself so many thanks for the video bud
I have this issue with my 1.2 fiesta!
My Ford ST has the same type of issue sitting about 2000 revs while stopped at lights, while I turn out of a side road about around 10mph the car continuously revs almost hit above 3000 revs. Also I'm not getting the acceleration I used to and it's not loud instead it has a loud whistle sound 🤔 Did you have any problems like this with your car ?
Oscarmike14 it didn’t ever hiss really, however I experienced similar idle issues, think mine went up to 2.5k max at its worse, if your hose is split it might have a massive split which is causing it to be so bad!
Eish Jay you make me want to rebuild my car, thumbs up!!!!!! but what could've been the common issue that spit the PVC?
Dj Stikzo apparently it’s just poor materials used that after a few heat cycles splits!
@@jaymono6498 its great that you are able to spot the problems!
Was it causing it to burn oil too?
When you start the car you get an amber light next to rev counter.i used to get this then one day I noticed it was red and has remained from then on.it goes out after a second or so just not sure why
Is it the small light to the right of the rev counter? I think that the warning light to let you know that a door, boot or bonnet is open!
Where did you order the hose and PCV valve from please?
Can I please have the link to buy the Valve?
Anyone got a link or part number for the actual valve? Cant find one anywhere :(
Is this the same on the 1.4
I cant seem to find the valve itself on ebay? I already got the hose and since im there I want to replace the valve to but cant find it anywhere so does someone has a link? :)
Well right when I posted this I found one haha, thanks google algorithm :p
tbf i think that would help me i can’t keep my leg still lol
Only watched this to see how the brake booster line comes off but you didn't show or explain that 😂 it's pissing me right off and don't wanna break it
Did your car ron bar in neutral ? So stationair? Need to know @jaymono
Hey mate I can't quite understand your comment!
It had idle issues in natural when stationary or in gear, if thats what you was asking!
Quick question do you go to Ashby tescos ? 😂😂😂
Somebody knows the finiscode of the pcv valve himself?
Do you diy paint plastic parts?😀if yes do u have any tip😀
They where recently sprayed just before I bought the car about year ago.
However I have sprayed stuff before - its all about the prep work, make sure whatever your spraying is properly sanded down / primed for painting, and have a steady hand!
I'm sure theres loads of guides on youtube though, I am planning to spray a few plastic bits, but that will probably be early next year!
Where can i buy that valve?
What the pcv valve number so I can get one plz and i no the pipe number
The PCV Valve number is 1251743, the hose I bought of eBay
Hi there would anyone be able to link the parts he used for this thank you
Hey, links are below:

Hope this helps!
how is your phone mount stuck, coud u show me a litte better :)
Lars K it’s a phone holder which replaces the coin holder on the car, so it’s build into the dash. DM me on Instagram (jaymono_) and I can show you a picture of it.
They’re made by a guy on the Fiesta Mk6 Facebook page
Where u get your phone mount from?
Chris 94 from a page on Facebook called MK6 Fiesta Phone Holders, he custom makes them to fit the coin holder slot and can do any colour you want
Thanks bud, just picked up a st150. Videos look great. Everything is fine just the temp don't seem to go halfway and drove it back 50 miles. Like the content great work
Chris 94 thanks! The thermostat are common to have issues on these, mine was exactly the same until I changed it. I’ve got a video of changing it on my channel if you’re interested. It’s not difficult at all!
Wank design 😂
