Hi very interesting, I have had lumpy idle, and limp home at traffic lights and junctions. having spent a fortune on changing valve guides, de coking engine put it back together problem was not solved. Having sent to to a dealer to find out more they reported that
" Renault confirmed an ongoing idle hunt problem with some examples of the
version. They recommend an new exchange engine."
Basicly it has Oval Bores in cylinders 2-3 having called them it was suggested when under warrenty the engines were replaced with this fault however my car is 5 years old. Renault uk will not assists a single penny as it is just out of 5 years old and 1k more than 72k.
I as you can imagine will never buy a Renault again as my previous Clio packed up as well at 5 years.
I feel for you . As far as I am aware Renault have never replaced the engines on these cars even if they were in warrenty .
As for getting to the bottom of the problem most of the problems you are suffering sound like it is fuel problem . There have been many people in this forum who have been ripped off by Renault and I also have learnt once out of warrenty take to a good independent . I had problems with my car misfireing low mpg etc lumpy idle . I found the problem with the misfire was Renault I repeat Renault fitting the wrong plugs and then telling me all my injectors needed cleaning . It was only when I took it to the independent they informed me of this and i had run the car for six months ;;;; . As for the lumpy idle I suggest all
owners when there car is next in for a service if there car is suffering with the idle problem to get the fuel pressure and flow sensors checked as this I feel when these are not working correctly people drive around in the vehicle unaware which causes of over fueling or under fueling which I feel causes the engine to idle lumpy as the
tries to keep engine steady . I also feel this problem may be behind the engine carboning up but hey I am no expert ...
I hope this input helps . Thanks
