Just going by its location just over the end of the camshaft, it looks like it is a cam position sensor. Not hugely familiar with the brand and been off the spanners in the proper sense a few years now, could also be an idle control valve.

That's the MAP (Manifold absolute pressure) sensor.

The MAP, that's actually what I thought it was, it wasn't in the Haynes manual but I just needed someone else's opinion, HellFireClub, I was hoping your answer on it being the isle control valve was correct!

The car is hunting and then regularly revs too low and conks out, until she's been driven a while at least, so bloody frustrating trying to find the issue!!!

based on your symptoms i'd recommend removing the throttle body and cleaning it thoroughly a small build up of dirt will cause poor idling and cutting out

Removed it the other day , cleaned it, replaced the two o-rings on it, at my wits end now, I reckon it must be a sensor

have you had a diagnostic check ? any fault codes ?

The diagnostic tool i borrowed doesn't do Renault go figure, but the cars own diagnostic throws up an error code of something along the lines of:

----h

this doesn't look like any code I've ever seen

Yes, it just throws up sites about the radio code, it had the engine replaced a few months ago due to the timing belt snapping (long story), the mechanic said he did a diagnostic check which turned out fine, I'm beginning to seriously doubt he did it now, small thing have been showing up which have come across coyboyish, for example when I took the throttle body off one of the bolts had snapped plain as day but its head had been stuck back on by mastic or sorts, I think I'll have to bring it to a dealer which I can't afford but looks like there's no other choice, I've come as far as a layman novice can go

is any part number written on it ? you could find in google.

what renault it is ? and what petrol engine size ? ill get my oul laptop with autodata.

As your car is a 2000, it might be pre-OBD which explains why the fault code may be illegible on your scan tool. The pencil coils on those things give a shed load of problems. Also, hunting up and down might be an air leak somewhere.

Yeah Nissan Doc is right, I made a stupid call there with that call! I'd clean out throttle body and service it for a start, it's an old car, probably not worth throwing much $$$ into it...

Do you know that didn't even dawn on me to do, I'll have a gander when herself comes back!

It's a Megane 2000, petrol 1.4, but heres something else, when the engine was replaced after the timing belt it was replaced with a 1.6ltr engine, is this even possible? I sent the other halfs father in to pick up a part for me and when he gave the engine number it came up as being a 1.6, the car is supposed to be a 1.4!!!!!

Whats the engine code on the block just beside the dipstick? K4J is a 1.4, K4M is a 1.6.
