OK here goes , search tried and nothing resembling my issue was found.
Daughters Clio 2 , 1.2 16v on an `06 plate with 75k on a D4F engine.
Around 60 seconds after starting the car (warm or cold) it starts to misbehave. If we are stopped then the idle becomes lumpy and you have to hold the revs >2.5k , if we are driving then if "feels" like a misfire . Once it has had its wee tantrum for around 30 seconds it runs perfect providing it is not switched off, if it is and is allowed to cool slightly then 60 seconds after the restart it goes through the same procedure. There are no faults displayed on the dash.
I am going through the fault finding process of replacing parts (cheapest first) as that is what a garage would do anyway.
So has anyone experienced the same issue and if so what was the outcome ?
I have replaced the inlet temp sensor , the coolant temp sensor looks new , adjusted the valve clearances , cleaned the MAP sensor , cleaned the TB which is a sealed unit with very limited access.
Questions - If a MAP sensor if faulty would it just "fail" and throw a fault message on the dash or can it still partially work ?
MAP sensors - new Ebay £13 , ECP £50 + ,has anyone had experience of the ebay ones ?
Lambda sensor - could it have a "dead" part in its sensing range and operated fine cold + hot but has a "blip" during the warming process ?
Throttle body - as there is no throttle cable and it is drive by wire via a servo motor does a used replacement need to be "coded" to the car ?
It doesn't particularly bother me whilst driving but as my daughter has just passed her test she starts to panic if it does it , which being an inexperienced driver is the last thing she needs
Any factual input greatly received.
