I HAVE CHANGED ISCV,DIZZY CAP, ROTA ARM,COOLANT TEMP SENSOR,SPARKS,

[Lunner]

Loose the caps please its annoying

Check earths, in particular the gearbox one

[diggs04]

opps sorry this better?!

yeah i will check the earths, cheers

[Lunner]

Yes :)

It wasd the big fat earth that you can see from the passneger arch that effected mine

Have you tried resetting teh ECU too

There is a sticky about about idle problems

[diggs04]

im new to this site "sticky"? whats that?

[BRUN]

was the ISCV you used a new part, because it is a common problem

if it wasnt new, did you clean it before fitting it

[Lunner]

Something that is stuck to the top of the section, so people don't miss it.

Found it in parts, guides etc

[diggs04]

oh right cheers. the iscv wasnt new but i did clean it up with carb cleaner and it defo works. as i tested to see if it opens and closes inside which it does.

[Lunner]

Whip it out and give it another clean, mine hads to be cleaned every few months to keep it running smoothly

[diggs04]

im thinking of buying a new one mine does look a bit old!

[BRUN]

there pricey, if it does work then maybe its not that

[ben_j]

did u change the correct cooling temp sensor. (u havnt done what i did and change the one that reads to the dash not the ecu one. doh. lol)

[mon]

TRY TAKING OFF THE IDLE CONTROL VALVE clean it it out ie wd40 brake cleaner .. or rust off then put it back on then see wot it is like .. the idle control can stick and cause this..

[mon]

ISCV ?? am i a thicko or is this the idle control valve?

[BRUN]

lol yup........ISCV is the Idle Speed Control Valve

[diggs04]

yes i did defo get the correct coolant temp sensor.

i tried re earthing the car, no change though.

a while back i did change the throttle potentiometer coz the wires were looking a bit shit and in the haynes it says when you replace this the intial postion should be verfied using a xr25 renault test box and well mine wasnt coz i fitted it myself. would this make it cut out?

[Justin..]

um crank sensor? rings a bell

[BRUN]

this can cause all manner of problems mate, it really can, i messed with mine once.........never again !

values have been posted on this site of how to set it up, get a multimeter and check yours

[VIPERONE]

Check that the retaining clip is on the iscv plug... if not then yout iscv will be slightly disconnecting hence it wont hold the revs up on idle ie clutch changes etc.

[diggs04]

i do have a resistance, volts etc meter that i used to check the sensors with is this a multi meter?

where have these values beem posted on the site? im new to this website.

[VIPERONE]

the actual socket that clips on the top of the idle valve.

[diggs04]

yeah i have checked that clip its fine.

[diggs04]

someone said the crank sensor.where is this and what does it do?

[Justin..]

i dont know, i know someone knows ? i thinks its crank speed sensor or something

[diggs04]

im gonna change the lambda sensor coz after listening to you lot i think it might be fooked ive looked on gsf website is it a lambda probe? coz thats all thats listed.

[BRUN]

dont buy a universal one, make sure its actually listed for the vehicle and doesnt just fit nearly everything

the crank sensor is on top of the gearbox under the airbox, can get one from any motor factors

[diggs04]

so where should i get one from? Renault?
