I fitted a pipercross filter to the join on the end of the air box and removed the standard filter. Although when I go WOT there is a bit of an improvement in pick up and noise, when I am cruising at any constant speed the car seems to hesitate ( as if it was misfiring) I changed my plugs last week and it had the coil pack recall last year.
Has anyone got any suggestions as to why I am getting this issue please?
Thanks
