clio 138
Bought a clio 138 two months ago with 3 month warranty it's full renault service history only done 45000 miles but on Friday I went to the shop then on the way home I give it a bit of stick in first changed into second and it started juddering the lower the revs the worse the judder almost as if it is firing on two cylinders. And the red engine light was flashing. Can anyone suggest what it may be. Also my average mpg before this happened was around 26 mpg don't know if that helps. And it did used to smell a bit petroly when idling. Thanks in advance
