    hesitation and really rough start..chugging.

    egr is fine, boost pipes are fine, swirl bar is fine.

    ive run injector cleaner through it, no avail....

    quite a loud ticking all the time, run some tappet cleaner through, no results.

    on idle revs theres smoke albeit a small amount coming from injector 1.

    ive done 3rd injector mod.

    so i decided to read the values
    yes cylinder 4 is -3.23

    cheers

    No isnt legal, as it then would have been vauxcom, as you are a UK resident.
