Renault Megane car stalls after 1mile journey wont idle

Car: Renault Megane
Variant: 1.4 16v petrol
Model Year: 2004
Categories: Running Rough, Starting & Power Loss
hi i have a megan 2004 1.4 16v petrol,
i bought this car for my wife as a cheap run around,

but when the car first started in the morning it runs fine.

but when after about a mile the car stalls a road ends and at traffic lights and when i start it again have to rev it to keep it running this is only for a few mins then becomes ok will idle ok and will be fine until i turn it off and let it sit for ten minutes then will go through the same process when it starts it stalls!

i have took to three mechanics but they are vauxhall and bmw mechanics, how ever they plugged the computer in and there is no fault codes and they changed my spark plugs and cleaned the throttle body out!

one guy thought it was the temp sensor! but wasnt sure

hope u guys can help or point me in some direction thanks

Temp sensor is certainly a possible as this could upset the ECM during the warm up phase and I have had the same issue with an Audi a3 which showed no fault code. Do you have a means of monitoring this sensor to try and prove it,s the cause a good multimeter may tell u if it,s playing up or if the cost is reasonable you could just replace it.Then I am not a Renault mechanic but a lot of the cars we work on share the same tech and work in similar fashion .If no one else replies with anything useful you could always run the issue past a Renault tech by going to a dealer after all advice is usually free.
