Mk2 Clio 1.2 juddering/misfire

Hi all,



I appreciate this question has been asked a hundred times and I've searched through the forums and found lots of useful posts but I wanted to ask before I go down the fault finding road.



The wifes 2003 mk 2 Clio has been very juttery both when idle and when she is driving it, loss of power, shaking gear stick etc, seems like a classic misfire.



After reading on the forums I suspected coil pack and spark plugs.



I plugged in a scanner tool but no codes came up, likewise the check engine light is not on!



I put the car into diagnostics mode and cycled through the messages on the dashboard where I can see the code

t--- which is injector fault



Could someone elaborate on that code more? Should I be going down the route of new plugs/coil pack or would I be wasting my time?



Thanks everyone
