Thanks Gareth BurgessGareth Burgess via Facebook wrote:I've just dealt with this exact issue so I hope I can help. My misfire was a combination of worn spark plugs, a failed fuel injector and a slipped cambelt.
I diagnosed the injector with the Diagbox OBD software although a fault code reader should be able to give you an idea.
The spark plugs are self explanatory. If they are NGK get rid and replace them. 0.9mm spark gap.
Checking the cambelt timing is a little more involved, if the injector replacement doesn't fix your issue.

You can find a Diagbox OBD from This Link (here) and always the step after the basic checks, it pays for itself with only one use

You can also find them on Amazon, by clicking here

There is a known fault with the injectors on some models you can find about that injector fault in this topic (here).
Bosch spark plugs are available by clicking here
