Faulty injector ?

[jhook661]

Evening all
Ive recently noticed I have a judder when cold and slightly better once warmed up
But runs fine with no Miss fire either so I'm guessing maybe a dodgy injector ?
I've changed
Spark plugs
Front pcv valve
Rev g diverter valve

Maybe some else had this problem and cured it any help would be much appreciated

Thanks for that Steve inlet manifold off to clean ?
How do you check for a faulty injector ?

If you take the inlet manifold off and look at your inlet valves, your see why your injectors will need cleaning too ;-)
