Car trouble 
Engine management light coming on randomly and flashing on my Clio (orange picture of engine)
Slight juddering when putting power in (happens randomly, sometimes its fine), inconsistent power, sometimes leaps forward, sometimes nothing happens. Feels like it's lost a lot of power in general, wont go over around 60 no matter what gear or revs I use.
Booked in at the garage today but just to reduce the risk of them claiming its something or not and getting taken for a ride, what do you guys suggest the issue is?
Thanks!
