My symptoms are back randomly.

Its the one where when the engines cold you dip the clutch at any speed in any gear (obviously lol) and it drops to about 400rpm feels like its gonna stall then crawls back up to 1k and idles perfect....

Then it hits a certain temperature or amount of times doing its little trick and idles perfectly time and time again.

I want this fixing soon if its the lambda because its the ONLY thing wrong with this car at the moment - it's a foooooking dream to drive and no rattles!

It's almost.. dare I say it.. civilised :shock:

whats it like from a cold start, just left to idle, does it idle ok for 30secs or so then chug a bit after a min ?

Daz i would say its your coolant temp sensor mate. I had EXACTLY the same problem in my old hybrid, and after a new lambda never solved it i then changed the CTS and it was perfect after that :D

It starts fine, idles fine, runs fine just till you let the revs drop from anything around driving speed revs if you get what I mean

If you let the car idle for 1 min before setting off when its cold, see if it does it then. Id be wiling to bet it wont :wink:

its the fooking road speed sensor daz boyo 8)
















can you manage the shoe laces now??? :P

Daz.

So now its the road speed sensor, the CTS and also the Lamda :lol:

dan-hipgrave
19-08-2007, 12:37
I stick by my judgement of CTS. It idles fine when upto temp so not a speed issue. This means it can only be one of a few things - the CTS, the cold start injector or the lambda. In my case it was the CTS and mine had exactly the same symptoms as yours does :)

Throttle Position Sensor obviously, sheesh. (j/k)

Is there an airflow meter on your car? If so, could do with a clean :)

I'll update on this - but for the last 2 days its been perfecto - don't need to let it idle or anything..

Maybe when its sat there for a day in heavy heavy rain its messing with something?

Last few days have been dry and I've used the car daily...

ECU compartment dry?

Daz.
21-08-2007, 18:59
I'm thinking that actually - it kinda just in a carrier bag at the moment lol

Daz.

Its back! :roll: :roll: :roll: :lol:
100% not the ECU, I've made a waterproof jacket and sealed the ECU so its deffo no that...

Looking at the sypmtons, and the answers i would say its an electrical problem.

:wink:

does it idle rough from cold? kangaroo style without touching the pedal? have you tried starting it from cold with the CTS connected, then the same disconnected to see if there is a difference. if there is no difference, i.e. runs really rough in or out, then i would suggest its the CTS. I had similar problems, so swapped my lambda, didnt sort it for long, checked all the earths, they were fine, jiggled around with the CTS and it vanished completely. was a loose connection, i did the abovve test and when out it ran rough as foook, when in it ran alot better, telling me it was working. if there is no change then obivously there is something wrong with it.

let us know how you get on

the flux capaciter is faulty, best go see the doc and get a new one! :P

From cold it starts up spot on first time everytime and settles down to a perfect idle..

Its only then on from setting off to the end of my road for example - dip the clutch and it drops the revs down..

I need to check its 100% not doing it when warm and report back - pretty sure its usually ok when upto full operating temps..

Noticed though that longer runs seem to make the problem go away for longer - I've only been doing the 1-2 mile journeys to work and back for the last couple of weeks and its been predominant

The only symptoms of lamba there are from cold, i'd go with the CTS option, or clean the ISCV if you haven't already done it

drsmith1979

does sound like CTS, do the above test to see if its faulty (start with it in, then out etc... seee if there is a difference)

the ambient heat from the engine can help alleviate the CTS issue, hence why it only does it on the short 1-2 mile journeys.

anyone got a spare? shouldnt be hard to change, besides they are cheap from GSF

Daz.
01-10-2007, 22:09
Might aswell get a new one if it is that - I'm off friday so I'll have a play with it then

BRUN
01-10-2007, 22:54
ive got about 3 old ones which may, or may not be working, you can have them all if i havent already thrown them away

Daz.
02-10-2007, 23:03
Much obliged.

Right once upto temp its perfect - I drove 40 mins this afternoon and it was spot on - car was left for 6 hours outside the missus' then started from cold and was perfect - another 40 mins back were the same.

I'm betting it'll be perfect again in the morining until its been sat for at least 12 hrs

Daz.
09-11-2007, 12:35
I'm actually going to do something about this now :lol:

Last few days it been pissing me off - seems the cold weather makes makes the gaps between driving the car is making the problem more common...

when it runs right - spray water up into both wheel arches and check the fault doesnt happen mate!

Daz.
09-11-2007, 12:43
Whats a CTS come up as on GSF's website?

or part code would be just as good 8)

Think I'll do this over the weekend while its dry and not in - degrees!

Ive started to develop this prob too. Not checked it out yet. Had a few comments off here.

Mine only tends to do it when damp/wet. Any particular weather conditions prompt yours?

Daz.
09-11-2007, 13:25
Aye when its been yanking it down :lol:

If its dry for a good few days after its fine

I park up my drive and its quite steep if that makes any difference

09-11-2007, 18:02
Have you still not changed that CTS Daz??? :lol: :roll:

Its all of 5 mins to change and then topup and bleed coolant system and for the sake of a few quid i'd do it :D

Dan

Daz.
09-11-2007, 19:01
^^^ No :lol:

Gimme a GSF code and I'll do it this weekend!!

Actually i may be of some help..found this on their site:

R93495 TEMP SENSOR-WHITE SQUARE CLIO 1.8 RSI/16V 9.50

I know it says valver/rsi but Williams one will most likely be the same.

BRUN
09-11-2007, 19:09
buy genuine, its about the same price as the GSF one anyway

Daz.
09-11-2007, 22:24
Ok someone give me the Genuine Renault code then!

and a rocker gasket part number too while your there :lol:

My dialogies has broken :evil:

How does a CTS look, and where is it on a valver engine? Because my car has the same problem, as yours, Daz.

dan-hipgrave
10-11-2007, 19:51
White plug on the thermostat housing. When removed its just a little brass round bit that sits in the water and its resistance changes with temperature.
