Help with Low idle and cutting out on my GF’s 1.2 16v

  • My Girlfriend has a 2002 Clio Expression 1.2 16v 48k miles. It idles really low sometimes and cuts out, worrying! :S

    Sometimes its fine but it happens even on warm starts, not just cold starts. Its really bugging me as I cant understand what it is. Today I dropped the oil and used engine flush, changed the coolant and flushed out the radiator, did the filters and spark plugs, still the same?

    What could this be?

  • My 1.6 does this and has done for months, no fault code logged for anything. Even after the 72k service with new plugs, filters etc it was still the same. Recently passed its emissions test too, so o2 sensors must be working of sorts.

    Come to the concluiosn on mine that the richness may be from an air leak somewhere. If it was coil related, I’d have thought the faulty one/s would have failed by now.

  • Have you tried cleaning the throttle body ?

    A quick search should bring it up for you.

  • It’s either on top of the bell housing or on top of the flywheel. Don’t know which.

    Looks like this.

  • I’ve exactly the same problem with my girlfriends clio.

    Changed the coilpack (comes wth HT leads attached) and although its improved it, it still hasn’t gone away.

    See my other post for a bit more detail.

    Its going into my mates garage hopefully this week or next to get a diagnostics done. Had it on the computer and came back with no error codes. Done an emissions test and all was fine aswell.

    Don’t know if its common but can also hear a «sucking» of air from behind the engine somewhere. Is this a common feature, never noticed it until we revved it ever so slightly & I had my head stuck right in the engine bay.

    Let me know if you find out whats causing it & I’ll report back with my finds.

    Yeah that would be great, if you find the problem let me know and if I find it il let you know! I tried to get a coil pack today, no joy! I can get one from Renault through a friend for £45 but I really don’t want to spend £45 if it isn’t that! Same with the tdc sensor coz that looks like a nightmare to change!!
