its been serviced,dv removed and blocked off,it will start and tickover at watever,but when i go round the block on a warm or cold engine,and shes come on boost/used the turbo,she idles poorly ,even cutting out,unless i turn the throttle cable adjuster out to raise the idle,then when shes left off for a bit,she then idles fast???

the fuel system is all new bits,ie pump,clean tank ,new filter,new injectors,new plugs,etc,its a new battery,fully charged,and fresh shell optimax,pluss new synthetic oil too,is there summit im missing,any pipes i need to check for air leaks?

help pleezy.

 

mate,all the pipes!breathers,mine dint tick over properly coz it was running to rich,check the hose from the left side rocker cover tht goes to the air box,plus check for leaks on the inlet gasket by spraying WD40 around it while it runs,sounds like a fuel problem to me,are all the plugs on the back of the block on rite?

 

need to check that,,failed to say,it has a kn direct to the meterhead unit,and the injector seals and retainers are new too.

 

tht wont hurt,when did it start doing it?

 

the other day,but to be totally honest,it aint had a good run since i got it,two year ago,as a project,most things have been replaced or done,barring stripping the motor right down and rebuilding it,as i was informed and is true that its quite fit,and is only hampered by this idle drop off,there must be an air leak somewhere,

 

normally u'd hear a bad air leak,i'd look at ya metering unit

 

will check"when my owners let me!"

 

Mines doing this exact same thing, its fooking annoying

 

cant find any leaks,

 

for now,till its had a good run,and mot,ill just put it down to the autochoke,and the idle set too low,was up and down the street,and it done it again,dropped to,just about turning over, so i upped the tickover ,to 1200rpm,and drove again,she seems to be tickingover fine now,when warm

 

I took my dump valve off and its cured it, cant believe it, ive got two baileys dump valves and both the fuckers leak

 

If everything has been checked and you have changed everything i would go and get it setup, thinking it would be pritty healthly ticking over at a 1000ish. Stood to be corrected but its just an idea

 

i had a similar problem on my rs,so i changed the electronic pressure actuator(on side of metering head)and it was fine afterwards.mind you it did run even better after a trip to power eng!!!good luck.

 

akito-man: You wanker can't u even get your car running properly

If i were you i would start disconecting parts of the breather system until u identify the problem. On a standard set up there is many potential air leaks, inclusive of the whole engine itself and the brake servo.........

I would disconnect the breather from the airbox and block it, and failing that disconnect the brake servo and block the manifold off but i wouldn't drive it too far with the servo disconnected obvio........dangerous as fuck

Good luck u wanker WankForceUK over and out!

 

if it leaks at the servo,is it fixable with a kit from fordingdales then, does seem to wheeez when its turned off around that area.


unchballs: unchballs: unchballs: unchballs:

 

In a word........
















NO!!!!!

New servo time. My cabriolet had a right fucking problem before, after idling for 5 minutes or so it would start to bog down and hunt, then if u revved it the alternator belt would start squealing, and if left to idle each the time the fan would cut in it would get closer and closer to stalling until it eventually died.

After much work and perserverance ive fixed a fuel pressure problem, disconnected the breather system and changed the break servo, and all is well

Do you know how to test your servo? Wheazing noise doesnt sound promising.

 

no! ,but seams to be ok ,fuel system,ie is new,pump inj,meterhead checked,kn,plugs etc

how expensive for the servo from henrys then,and are they available still?

 

No no no no no i'm not saying you have a fuelling problem, among the problems i also had very poor starting, had to start it a few times when cold, but when hot........OMG u had to crank for about 5 mins because of the lack of fuel pressure.

To test the servo:

firstly run the car, and push the brake pedal and switch off while depressing the pedal, and you may feel the pedal pushing your foot back up,

second test, run the car, switch it off, pump the pedal (u should hear sucking/air noises) and the pedal will get harder, do that a few times then hold the pedal in and re-start the car and the pedal should go down a bit once running.

If u can feel the pedal forcing your foot up on switch off, and if there is no vacuum noises doing the second test then the unit isn't holding the vacuum and has an air leak.

U should also be able to pull the pipe off the servo and hear whether its retaining the vacuum pressure or not, i bet it doesnt if your getting this wheazing noise.

The tiniest air leak on the KE system causes MASSIVE running problems, i fucking hate it, it pisses me off, im going EFI end of story end of problems everyones a happy easter bunny

As for prices, i really don't know, i bought a cossie break kit ages ago off ebay and it had a literally brand new servo with it all, my old one was completely fucked though, it was the original one though it had done well, 21 years of service. If ford dont stock them anymore u will get a third party one.

 

will check,when the sun rises geeza

 

Sorry thats not good enough i suggest u drag your sorry arse out there now and do it

 

rite, done the checks,and it only pushed s bit,but there is a leak at the bottom of the servo,
now i dont know if its the seal where the master cylinder locates onto the black servo ,or if the servo face has perforated,enableing air to pass,,if i disconect the master cylinder from the servo is it gonna spill b/fluid everywhere then,should i drain it first?

its defo not,

leaking at the rear of the servo
leaking from the resevior(obviously)
any air pipes attached to the engine,
air pipe to the servo is not leaking either.

wot now ?

 

To be honest if its leaking then it'd be best to just change the servo. I had a car that it was leaking between the master cylinder and the servo, and i couldn't stop it for love nor money and it made that wheazing noise when i switched it off.

The one ive just changed had no obvious signs of leaking but a new one has made it so much better.

U can undo the master cylinder and pull it forward worry free*

Is the vacuum pressure being retained after switch off then?




















*Not a Guarantee does not affect your statuatory rights

 

well sort of,it pushes a wee bit,but maybe cause of this leak,ill tek it off and give it a clean up(servo) and re-seat it with something sticky and strong,

bearing in mind,ive got,new cylinders on the rear,new calipers on the front,new brake hoses,(copper) new goodridges too, ill get my thread up and youll see the stuff ive done,.

s2 wont run ,finished for now. -akito-man

 

Well if its retaining the vacuum, u shouldn't feel the pedal rise at all,and u should be able to walk out to it now and push the pedal down and still hear the air noises. Did u pull the brake servo pipe out and see if the vacuum was still there?

So, let me get this straight, your going to clean it up, and re-seat it with something both STICKY and STRONG

Just get a new servo man, i bet its the orignal one the car came with anyway, if you've put a whole new braking system on why not just change it and make the set, i think off the top of my head they're about £25, chances are if u seal the front it will spring another leak somewhere else. Cutting corners never works in the long run.

But before you even do that why don't u just disconnect the servo pipe and block it at the manifold and see if it runs then???????

 

aye,pulled the pipe out of the servo.blocked it with me thumbelina,and it ran better i must say,down to henrys for a servo tomorrow then,if they still have em,or the factors.

 

There we go then The one i fitted on mine im 99% sure was a third party one, looks the same though AND its powder coating as opposed to paint, which was EXCELLENT when i spilt brake fluid all over it

 

spilt fluid,you waaaaanka!

 

Fuck off it wasn't my fault

I'd just spent ages doing a 2wd brake conversion and to my "sheer and utter delight" the pedal was hitting the floor with just a "hint" of braking. And i had put a 2nd hand 23mm master cylinder on as mine had a 22 so i figured it must be that, so theres me being all careful changing the master cylinder (spilling my expensive 5.1 braking fluid down the servo) to put another master cylinder on, and guess what, it was exactly the same

 

rite,update, servo from ford is £120.+vat,

partco dont do them

and my motor factors will get back to me tommorow if they can source a supplier and a price.

 

Come on give me some credit i was close, only missed a 1 out

Worst comes to worst i might be able to sort you out a good second hand one, or that said maybe even mine actually because its coming back off at some point, changing it for something else completely.

 

is it an exchange item at the motor factors,forgot to ask?

ill tek mine off and have a look

 

What do you mean are the motor factors ones exchange???

Take yours off and have a look at what???

 

servo, my calipers where exchange items,

my old uns for new uns,they go back to be fully reconditioned and sold again.

wondered if the servo unit would be re-dressed ,and sold recon,not as much as new ,but juss as good.

tek it of to see if its split,or juss needs sealing.where the master cylinder goes.

 

Ah i see, calipers are usually re-conned because they are cast items, things like servo's are pressed steel so i doubt it very much, plus the fact they are pressed together aswell so they can't be split without making a pigs ear of it.

Its worth a look but i couldn't stop that one i said about leaking for shit. Its the usual rubber seals story, don't last forever Fairplay if u salvage it but i don't reckon u will.

 

ebay update,the ebayer asking the ANAL questions about reserve prices,is only selling the same fookin thing,but dearer,cheeky git,mines got 4 days more than his tho.

i asked if he would do a buy it now price! just to let him know

ill let you know about the servo tomorrow.

 

LOL what a prick, ive never thought of that before lol.

Set up a bogus account and put like a grand on it just for the comedy value

Speak to u in a bit

 

took off the servo,and wot a foookin big wanker you are

you where rite,the seal around the push rod is the leaker,

but in a years time the lower "bowl" would have rotted through anyway,

ordered one from ford,£120+vat,

tried everywhere to no avail,scrappys havent seen a mk4 since like "yonks" ago,motorfactors,tried,lucas,beringer and a couple of others,but all said no!,manu part .

so,im gonna split my original(coz im like that) and see if i can offer up somekind of substitute for an air seal,then weld it back up,and pressure check it,for a laff. you never Know,might start an exchange buisness,,,,,not.

 

Well wanker it is if thats what being SHIT FUCKING HOT takes

FFS man everyone i speak to about scrap MK4's says that, i could get you as many 2nd hand ones as u want here........duno whats goin on.

£120 FUCK THAT for a game of toy soldiers

 

ordered ,here on tue,

another receipt in the pile.

 

makes me glad im changing mine altogether for something else

cant get over that £120 jokers
