clio 182 starting issue

[hperformance]

i have a 55 plate 182 and have a starting issue

the car will start fine 4 in 5 times, but on that one occasion the car will build up revs and suddenly drop and cut out

the car has gone into renault today but they cannot find a issue

anyone had this?
cheers

Try cleaning out your throttle body and disconnect your battery for about an hour to reset your adapitives
