They do this on full lock to prevent stalling.

Really feint hesitation/miss at light throttle

2003 Clio 172
Yeah....but my revs don't go up at all....just down :/

Try bridging the connector.
Ph2 172, 106 Rallye
Good meeting you too man! The car drives lovely, Idle's a little high but that could be the map. The rev's not holding when you hold a stable position on the throttle was a concern though.
Anyone think it could be the throttle body or the actual throttle pedal position sensor itself?
Another thing J was talking about was perhaps the VVT solenoid was stuck on? Is this a possibility?

You can test the dephasher solenoid in the Actuator menu on the Rstuner ?

Hey @JamesBryan yes.....and when I do I can hear it clicking. It was just odd that below 2k how it was impossible to hold steady revs with the throttle.
I was able to do this just fine in Simon's car.
Above 2k no worries.

You can see the values of the throttle pedal in live data, see what they're saying.
Another thing to add to the parts list.
2003 Clio 172
Hmm......I did not do that.................err............................it was Simon's fault 
We were probably talking too much.
Ok, so car warm.....................i hop in and press the pedal to bring the car to say, 1700rpm..............after a couple of seconds it will drop to say 1500, then back up...........then down, then back up............................for ever
I have a sneaky suspicion that this is tracking with the lambda pulse

Gonna try shorting it out.................it wont 'splode will it?
No thats fine its just a switch.
PH2 172
Got to be done if there is a weep.
Power steering runs about 90 bar, before you know it, the centre has shot out the switch, steering pump seizes and the aux belt ends up in the cambelt.
PH2 172
Sorry, I just thought you should be aware.
This is the primary reason for converting to EPAS on a track car.
PH2 172
If it squeals on full lock when stationary, particularly when cold, it will be the aux belt/tensioner.
My pump does whirr a bit when cold, but it`s been that way for 40k miles.
Don`t panic.
2003 Clio 172
It does it when it's cold if I have to put any effort into steering.....not just at the end of travel.
Little or none when warm
PH2 172
If you mean squeals, RPD have got full aux belt kit on sale.
https://www.renaultpartsdirect.co.uk/parts/special-offers/renault-clio-172-182-auxiliary-belt-kit/
My apologies that this link will not work in 3 weeks time, and will probably be for a wheel bearing if it works at all, but that`s down to RPD, not me.
2003 Clio 172
lol................yeah..............RenaultPartsDirect have had a fair bit of my money to date anyway.........what's a few more quid.
Will probably need the wheel bearing (or any other part it changes to) as well if it keeps up like this so that is no problem
It's an odd squeal/screech.............not what I would typically associate with a belt...........will try and get a video of that too for your viewing pleasure...........I mean, I am sure you are all loving it.

Never heard of this happening, got any links?
2003 Clio 172
Any way to verify the belt/tensioner for sure before buying the lot and realising its the pump and having tensioned a belt already?
Tried a wee huff of wd40 on the belt and it didn't stop the racket when i tried earlier
If we do end up down that path, any of you lovely lot have a pas pump lying about for sale?

The squealing/screeching could be the crankshaft dampener pulley starting to separate. It’s definitely worth a check, as I thought my pas pump was on the way out, but it was actually the crankshaft pulley that was knackered and making the horrid squealing/screechy noise.
2003 Clio 172
Hey @clio_ross
That was one of the things that i did replace in this veeeeeeeeeeeeeeeeery long thread
Mine was starting to spin freely (marked it with tipex and noticed they had spread after one day). I was also able to super-duper check the timing when I was doing this
Cheers for the heads up..............IMO.............everyone should be checking this on these cars now.

I believe it was @barnesautos that told me that it is the sender that fails.
See post 15.

Also fairly proud of my hand-crafted-without-a-welder aux belt tool.
Just undersized a square hole in b and q finest hunk o metal and pressed a bolt that I ground to 10mm square into it with a vice.
Made a second 10mm fitting with a different angle as I couldn't work out which would work best.
Tinkering!

The square holes on the tensioners are pretty weak, seen loads crack.
The 100mm jubilee clip works well.
