Hi

Renault Clio Dynamique 1.2 16v 03 plate.

I'm also having problems with my Clio and rough idling. When I start the car the revs sort of "adjust" up and down until they sit at about 1100, and after I've driven for a couple of mins it dips to about 500 revs and starts juddering like a mo-fo. To help I'll give you the history since I had the car.

When I first got the car last August it seemed to be running fine. Then one day the Toxic Fume light came on, the car lost power (wouldn't go above 25mph) and was idling poorly. It was still under warranty, so I took it back. They changed the spark leads & plugs. It ran great for about 2 weeks and then the idling came back, and the light came on again. So I took it back. This time they said it was the Low Oxygen sensor. The idling problem was still there and by this point I'd heard it was common so I STUPIDLY left it. Recently the TFWL came on again. I took it to another garage who said it was again the Low Oxygen Sensor, so it was replaced. The idling was still a problem so I went looking to see what I could do about it myself, as when I spoke to the mechanic about it he dismissed what I was telling him, what with me being female. :steam:

I got my mate round to have a go at disconnecting and cleaning the Top Dead Centre sensor, which we did. It improved slightly (it now doesn't dip below 500 revs) but the judder is still there. :confused:

I've read that I should take out the ICV and give it a good clean with carb cleaner, however I don't know how big a job this is. I've read that it's attached to the throttle body, does the whole throttle body need to come out? Also is it an easy job for an amature armed with the Haynes manual, or is it better to take it to a garage? Do I need any specialised equipment? Where about on the engine will I find the throttle body? Is there any pics on the forum that will show me where it is located? :confused: :confused:

Sorry if I sound like an idiotic woman, but if it's not a hard job then I'd rather save my money and ask my mate to do it. I want to sell it, and don't want this obvious judder to be a problem.

Thanks again, sorry for the length! :crazy: Any advice is greatly appreciated!

Sounds like a faulty throttle motorised throttle body..
but could also be caused by one or more defective spark plugs, this is a very common problem and would be the first thing that a dealer would replace to cure this type of running problem..

If it turns out to be the body then it is bolted inside the inlet manifold and will take about 1 hour to remove..

Generally the body is not repairable, so a new one will be required..

This is also a very common problem with the D7F engine and there are a couple of Renault tech notes that cover it in detail..

Thanks!

The car is in for an MOT today, so all going well it won't affect it.

My mate's boyfriend is a mechanic (works mostly on vans) so I'm going to ask if he fancies doing it for me - sounds far to complicated, and I don't want to make matters worse.

Any idea on what a new Throttle body will cost? Does it come with a new ICV or will I just get the old one cleaned up?

The first time I had problems with the car they changed the spark plugs & leads, but it was only good for about 2 weeks. Surely they should last longer than that?

Thanks again

Egowie :d

I would most certainly replace the TDC sensor located RH side of engine block near the top. Very common fault causes all kinds of problems-with the electronics/starting/acceleration/lights etc etc.

Simple job especially as you have a friend mechanic.

Hope this helps

our clio in garage now same symptons and it si lamber sensor and tps on throttle body. rough idling down to overfueling thats why you toxic light is coming on. renault wont just sell sensor attached to throttle body they want to sell the whole body with sensor on it but if you search you can buy sensor seperate. i read so much in the past month oh its this its that but all wrong go for the lanber and tps mate and your probs will be sorted. the longer you leave it the more chnce you got of wrecking the cat so more expense. any help just pm me. i have a bill of about £500 coming today and no wiring fault at all, good luck

I had a similar problem, cleaned the throttle body and the idle sensor was very "dirty". Cleaned that too and hey presto. I certainly recommend anyone suffering idle problems, to clean the throttle body and idle sensor while you have the throttle body off. Cured my problem!!

Re: Clio idle,
On your exhaust catalyst there is a sensor near the engine disconnect the car battery and disconnect the sensor than remove sensor with the right size spanner than clean with wd40 and give it a little sand with fine sand paper than spray abit ov wd40 on it and in both connectors put it all back connect the wirers and than connect the car battery wait ten minutes than start the car leave ticking over for 15 minute than should idle correctly.
P.S let me know if that worked ???

Hiya....... Couldn't be anything as simple as a frayed or sticking throttle cable could it.....:confused: Have you checked it runs freely on the pully......Can you not adjust it~? I am new to Renault, maybe grabbing at straws here.......But, surely, the first port of call is to make sure that accelerator cable is working correctly..:confused: Of course, I may be way off the mark here and other posts spot on..... But IMO, always start at the begining, the easiest and cheapest fix and progress from there.....Stacey.

Re: Renault Clio II - Engine - Idle problems DF7

Hi we have a 1.2 8v DF7 engine Clio Grande which had the same symptoms.
We changed the throttle body as the electrical connections are integral and can't be swapped independently. the fix came as a surprise...... Blown head gasket! We had mayonnaise( oil water mix) all over the throttle body. I checked inside the oil filler cap and there was way more in there. Mayo wasn't apparent at first it was only a fortnight from when the problem started to the head gasket problem discovery.
Cars fixed now and we were due to sell, but someone ran into the drivers door......they left their details so we can contact them......i know, i know i nearly fell flat on my face. We need to swap out the old door for a new one. Does anyone know if a 2001 -2006 door fit a 1998-2001 car?? will the wiring loom on 1998 car fit a 2001 door window switch? i have been advised to check the outer plastic door protector/ strip as they are different.
