Missing fault

[simonb2007]

Whe n you are excelorating even gently sometimes it will kind of get stuck in the revs and misfire really badly. if You keep your foot down it will shoot off after a while. when this happens it gives a lambda sensor fault code.

However i've change both lambda sensors and done a service including leads.

Anybody have any idea what could be causing this?

Thanks

normally leads or plugs are fucked

Had both new in the last few days.

You think it could be the coil pack in that case?

thanks
