throttle sticking open

[rich19]

lately i`ve noticed that my throttle is sticking open and while pulling up at traffic lights etc i have to put my foot under the pedal knock it upwards to get the revs back to normal idle

is this a problem with the cable or the pedal or neither


any advice

cheers

Mine did this it was the cable fraying by the pedal and was getting caught. Check the cable ensure its intact. Maybe get a bit of lube on it if it is

Idle control valve??

 

[rich19]

i`l check the cable after work, where is the idle control valve located alan?

Your asking matey...

That i've no idea of...its just a sort of commen problem with a lot of cars that have a cable throttle..

 

[rich19]

useless

i`l have a butchers and look at the cable mechanism but if i`m not honest not a clue what i`m looking for } )

ICV is on the back of the inlet manifold next to the TB. its black and had VDO on it.

99% sure its a cable though.


check at the pedel end and at the TB.


if its not then clean the ICV with wd40 . its held on bu two torx nuts

cheers ben, if its the cable how easy is it to replace/ fix?

cheers ben, if its the cable how easy is it to replace/ fix?

20 min job.

jack up the drivers side,
wheel off
back of the arch liner off
back in the car and unclip the white clip from the pedel
remove the cable through the bulkhead
make note of its path to the TB as if it isnt routed correctly then it will still stick
unclip from the TB (dont loose the steel clip LOL)


re fit in reverse order

mine was a ringer then LOL

 

[rich19]

sounds simple but i have a special ability to muck things like this up!

where can i get the cable / price?


cheers

 

[ben_p]

renault £17 + vat


trust me its easy

 

[rich19]

trust me i`m crap

 

[rich19]

meant to ask someone where the cable comes out of the throttle body it goes through a 3 inch plastic cylinder before heading down to the bottom of the bulk head

is this a kind of adjument/ tightening mechanism cuz it appears you can twist it

i maybe talkin utter sh**e tho

 

[ben_p]

LOL well a garage will only charge £30 to fit if not


check the cable for fraying first mate (both ends)

 

[rich19]

i`l check for fraying then, is it normal for the accelerater pedal to be able to lift right up unlike the clutch and brake which only move the one way?

yes, it has a clip on it to take up the slack of the cable.

does yours have the steel clip which slots in the grove?

yes thats normal as the cable just flex's its not on a solid mech like the brake and clutch

not sure i`l have a look, do you just twist or is it more complicated than that?

 

[ben_p]

nope it just unclips (pulls off)

 

[rich19]

so can i adjust it anyway using the black bit, earlier you mentioned dont remove the steel clip is that the one you were on about

 

[ben_p]

yer, try that too. i ment to say when you remove it.. Do NOT loose it as you can buy them unless you buy a TB for £300 iirc

 

[P111LTL]

This is a common problem by the soundsof it as my old phase one did this most annoying and its definately a cable issue.

 

[rich19]

now your making me nervous ben

so just twist ity and it should take the slack out of the cable?

without sounding like a complete dribbler (probably too late there) do i remove the clip before twisting ot leave it?

Look in the guides section M8. I posted a guide to changing the throttle cable recently. It will be the cable that's the cause.

[ti_172]

Did this fix your problem Rich19?

Thanks in advance

dont complain! you just get everywhere a bit quicker!

Cable would have to be pretty rubbered to cause it to stick open so a quick look will confirm for it fraying.
My guess would be the common ph1 172 problem of the Throttle Body spring becoming baggy.

I'm not convinced that there is a common ph1 172 problem of the Throttle Body spring becoming baggy. I nearly bought a new TB because my revs wouldn't drop down, but then I just changed the cable (it had been changed 3 months before and was fine until I messed about with it) and I carefully routed the new cable behind the bulkhead soundproofing so it felt really smooth. It sorted out the problem and has been fine for a few months now. It saved me £200 quid!

The springs does get week over time and a you need to sort it out some people are lucky and don't though.

Mine was fraying on my ph1 before so I replaced with a new one and it's spot on now, much smoother. Not that hard to fit in the end.
