Laguna 2 Fuel Injector Trim/Flow problem?

Hi,

I have a problem with my car and I need a bit of help diagnosing the problem. It's a 2003, 2.2l Turbo Diesel Renault Laguna II.
When it idles, especially when first starting up it's very 'lumpy' and feels like it is trying to shake itself to bits. Driving is fine, it's only when it's idling.
I took it to Renault who said they could not find any faults through their diagnostic computer, but had a look at the live injection data. I have uploaded a couple of pictures of the CLIP printout here:

Do you agree with the testers diagnosis and solution? Thanks

Well I gave it a good thrashing home last night and the problem seems to be a little better. I don't usually drive it carefully but last night I really went for it. Maybe some redex will do the trick

Hi Fwk.

Sorry no-one has got back you on this.


It would probably be wise to start with a bottle of injector cleaner (in with a full tank of fuel) then seeing as you said a good thrashing has improved matters a little.

You would see immediate results, but if its gonna help, then it will after a couple of hundred miles or so.

Welcome to the forum by the way.
