Hello again John - Thank you for your reply and info...

First my sincere apologies that I could only just get back to you just now...

Ok - with this engine / management system that you have, there is a known / common issue with these that causes a known stalling fault / problem ..Renault in fact issued a "FIX BULLETIN" on this for this very fault - I will give it you as follows so that you can get your car sorted - it is as follows for you :


Affected vehicles

Make/Model : Renault Megane II (02-10) 1,6 2002-09 Engine code : K4M 760/761
  • All petrol models with throttle control unit.
  • Engine stalls.
  • Poss Loss of engine power.
  • Throttle valve not opening or closing correctly due to build up of deposits in throttle body.
  • Remove throttle body and clean deposits from inner walls.


So its not a core plug issue or anything like that ... I would suggest to make a check of all the pipework - for any loose fitting pipes - vacuum pipes and even electrical connectors on the various wiring / sensors on the engine and earth wire connectors first - as anything like that can cause such issues too.... But after that- if its nothing like that , then have the throttle body cleaned as above to cure this known fault. Any small type good garage can do this for you if you would need garage help - but either way , given your description of the issue, that will cure this for you.

Let me know if you need anything more on this at all -
