My car idles fine for a few mins and then goes a bit lumpy it doesnt die just sits bouncing a tad around the 50 mark (x100)
Also theres a bit of white smoke not a lot
Checked the MPG and shows 9.2 ??
Car runs fine is it too rich?

Things I have done :

Renewed :
HT Coil packs and Leads (1 unit)
Spark Plugs
Changed oil and filter
Cleaned throttle body (wasnt extremely dirty)
Checked wiring in the black box and around it seems fine
New Air filter
Full Tank of fuel
Tyre pressures are fine and no brakes binding

Car is a Renault Clio 1.2 16v Dynamique 2002
with 73K on the clock
Am going to get the timing belt kit and water pump done once I figure out this issue.

Questions, where are these in the engine
PCV Valve?
Map or Maf Sensor?

People mention the O2 Sensor I can see one at the cat and the other in the centre of the exhasut which one is the O2?
I tried cleaning these to see if it makes a difference and nothing...

Theres no warning lights on dash apart from SERV and AIrbag light, dont get me started... nothing else

Changed Lamda Sensor Universal type and fitted within 15 mins
Car seems to be running no to shabby and less white smoke

But had no errors on dash screen showing this as a fault with eng. management light or whatever
Also boosted me to 47 mpg around town :beer:

Just incase you guys have the same issues this is the Sensor I purchased LINK

So just to clarify idling issue, white smoke :

Change Coolant Temp Sensor as mentioned by user
And Centre Lamda Sensor (bank 1 sensor 2)

Thanks for the help guys its appreciated :d now for a drink :lager:
