Has anyone any ideas on possible fix. Engine misfires on start up hot or cold. No fault codes stored. Checked and fitted new glow plugs. Then rechecked, fitted new injector seals and rechecked. Have tried to find someone to check injectors but no one seems to be able to check for me.

Local Range Rover specialist thinks someone up north can check but cannot remember details, other local diesel specialist says only landrover can check with oe scan tool ?

Thanks

John
