isit running lumpy all the time

had one in the other day that all it was was leads and plugs as once they get a load on like at 3000 they fail and is doing the same as a bloke at works car and thats plugs but he just has to get the money to fix it

they might look fine but you cant tell what they are doing when sparking

as you have done all that work i would change the lead and plugs and fuel filter

Is this the GDI (gasoline direct injection) engine?
