I didn't know this, maybe you didn't either!
I've owned a 1.6 VVT 53 28,000 for nearly 6 months now, and it hasn't quite been the match made in heaven!
First i had the inevitable dephaser pulley (or as the rest of the world knows it the VVT) fail withen a day of having the car. The trader of course paid to have it fixed, but my confidence was already slightly knocked.
A big improvement obviously, but still i didn't feel i had any power in the car, it was lumpy in pulling away, and just seemed to at it's own pace. Plus it had still a problems starting, revving up then dying out.
Then in quick succesion Full Service, MOT, Camshaft Sensor. i was thinking that must have got it, fluids have been changed, sparks, camshaft sensor, plus they checked over the ignition coils. It did feel kinda better, psychological ?
All confidence drained now, resigned to the fact that i've bought a friday afternoon car from a model that's plagued with faults anyway.
Last chance, after checking over the forum and looking at a youtube video i thought i'd change the TDC sensor. Even the garage said that the part had been modified because they had been faulty. Surely this was it. NO, a few days later the car started then the revs died almost to stalling point.
Ultimate Last Chance. I took it to another Renault garage, they obviously wanted to the to obligatory clip test, which obviously came back with no errors. But then the mechanic said did i want the THROTTLE HOUSING cleaned? Right this is the very last thing, so i agreed.
Now after all my troubles with this car, things might be psychological. But i'm not joking when i say i'm driving a different car. I just wanted to stop the starting problems, but i feel like they've chucked in a few more horses into the engine. When you put the foot down it goes, when i'm pulling away it's smooth quick and responsive. TOTALLY DIFFERENT, even te mechanic remarked what a difference it had made, and they never normally say anything.
It's still early days, but it cost me £49 inc the clip test. And it's made the biggest difference. I reckon the while the dephaser pulley was failing crap was building up in the engine and then being sucked through the throttle housing, you'd never normally have to have it cleaned at such a low mileage.
To anyone still having performance issues make sure you get this done.

Cleaning the throttle body is a known problem on the 1.6 and 1.4..
On this type of body the butterfly does not completely seal the plenum as it is designed to allow air past it for engine idle.. (replaces the idle control valve).. If the body or butterfly edge gets sooted up then the idle air supply is reduced and therfore induces stalling etc.. Cleaning cures the problem..

clean it with carburettor cleaner spray / cloth.
the bit that is been discussed in where the Air intake goes into the engine, so it is at the end of the tubing from the air filter that goes around the right hand side and back at the top of the engine.
i'm not sure which bits you need to remove as i don't have my haynes manual handy at the minute.
I do have a haynes manual, if i can find a good picture i'll post it up. But it won't be till monday now.
By the way the car is still running brilliantly one week after the cleaning. But i'm still not holding my breath just. At least i'm enjoying driving the thing now.
The more that know about this easy fix the better. Especially as it seems that it could be something most people can do themselves.
My mates are all stumped, yeh they know that cleaning the throttle housing needs to be done occasionally. But normally to old cars, or at least never before 40k. How mine got so stuffed up in 4 years and 27k miles, is worrying sign. But i guess i'll never know how the previous owner drove it.

In my experience, the throttle body needs a good clean every 3-4 months.
I clean mine every 3 months (I remove it and use a soft cloth and carb cleaner)
I spent the last summer driving around in the city (clocked in about 7000kms in a 3-4 months)
I could tell immediately that the throttle body had been clogged up.
So I removed it and I couldn't believe the amount of soot that had accumulated around the butterfly.
Cleaned it and everything's fine now
There's a nice picture guide on the how-to section of the forum I think
