Misfire problem

[Weejok]

Have had my airflow metre replaced and also lamba sensor 2. Still continuing to misfire at 5000-6000 rpm. Think it is also over fueling. any ideas to what the problem could be? thanks

could be a coilpack breaking down underload

Ok cheers. could it be the first lamba sensor?

 

[Cupra20]

have you had the codes read yet?

yes ive got a fault finder thing. it was showing air flow metre so taht was changed and running a bit better but still not right. its not showing coilpack so hopefully not that. got another lamba sensor coming so hopefully have some luck with that. cheers

see how you get on with the other lamda fitted, if that don't sort it then i'd have i look at the coilpacks if it was me, i take it it's a cupra?
