Clio 172 rough idle what to do...?

[Pusiak]

Hi,
I have a problem with my Clio Sport II ph2 2002r. My car has very rough idle. I changed a lot of components : New spark plugs NGK, new OEM leads, new OEM timing kit (with dephaser) changed by dealer mechanic, new coil pack, new air filter, new pre cat lambda, checked compression, cleanes throttle. Theres no faults, only too high manifold pressure... it does not matter whether it is warm or cold, engine always worked like with sport camshaft with poppy noise from exhaus on idle...
Here's the video:
Please help
Cheers

they all have a bit of a lumpy idle to be honest. Mine has always done it.

Assuming it's on standard cams, get the timing checked by a specialist.

Like i said : Timing is new, changed by a Renault specialist, on the previous timing kit was the same problem.

I wouldn't worry.

You actually said it was done by a dealer mechanic, most of which get them wrong regularly, otherwise I wouldn't have mentioned it.
If it was me, and still assuming standard cams, I'd be going down the line of timing check then compression check.
