Hi

What is your history with the car?

Any work done recently?

Are the fluid levels all holding ?

Is it in regular use.. or parked for extended periods ?

recent purchase, full history, it seemed to have a city steering problem then we changed the altanator and that seems ok, all fluids are fine, kept in a dry garage not been used as you can only drive about 100 yards and it starts doing it

Hi

2007+ cars are fussy with cambelt 'time'

If it has been changed just before your purchase.. that MIGHT be related

What Codes is it logging?

Where are you based?
Plugging in with proper software could sort it cheaply

based in the highlands, it runs fine on start up, its just after 2/3 miles it starts misfire to a point it stops
