Good afternoon, looking for some help! My Skoda fabia mk1 VRS has developed an issue we’re it will suddenly start to shudder the whole car! It’s like an engine miss firing but if you stop, turn it off and on again it’s back to normal! If you don’t turn it off it continues constantly only off and on stops it! Any ideas? Thanks 

It sounds like an injector is playing up, there should be a fault code to tell you which one.
