It seems to happen more when I've driven somewhere and turned the engine off for a short while, When l turn it back on a warning light comes on (electronic fault light l think). It just cuts out unless l keep the revs really high. It is so frickin annoying! l also noticed a kind of sulphur smell when it happens. My neighbour works for Renault and l paid him to put it on their computer, he told me it was to do with a faulty sensor and replaced it. This was a few months ago, but it has since started doing the same thing. It is also started happening mid journey. Any suggestions? Thanks.
Just do not really have the money to keep sending it to the garage. Just wondered if anyone else has had the same problem, and what it turned out to be? My bro is a technician and good with cars - maybe something we could fix??

Take it to the garage it has a problem with it.

H l YA SOUNDS LIKE blocked cat probably over fuelling really needs to go on the machine to get fault code
