2.0 clio sport
When I keep revs at a constant . Eg 2000rpm , car really holds back , it does it at any rpm u choose , if h put your foot down it shifts but not like it did , had new plugs fitted and no difference , been on computer and bloke says it's fine , but it used to be more responsive , and didn't 'choke' up like it does now when u hold it at a constant rpm , any help as I'm a beginner with these cars , (at 44) . Thanks
