    Default Hesitant after water pump change

    Had the pump changed yesterday.
    All seemed fine when I had it back and when he was running it.
    Once I drove it it seemed a little slow.
    When trying to go up the revs around 3000 it seemed to slow a little and then go normal at 3500.
    Kept driving to see what occurred.
    When I tried accelerating again hard it felt low revs and then engine management kicked in. When stopped at roundabouts it was stuttering as though it was going to die. Didn't though
    Turned off and started again it cleared.
    Came on 2 times more and now stays with the car still running a little sluggish.

    I would have thought EGR either gone or needs cleaning.
    Does this sound right with the symptoms?
    Nothing else seems of issue.
    If so what would be best, clean the thing up or blank off??
    I am not asking for pages of opinions as I have seen the discussions about blanking this.

    thought the water pump was driven by the timing chain on these , although I have never replaced one s couldn't say for certain what is or isn't involved

    Misfire in 1 and 4.
    Fault now cleared and not come back.
    Either faulty ignition coil or I think a little left over water from the seal gone on pump.
    Will take plugs out and clean them up (still only 2 months old) and see what happens.

    Oh, and pump is connected to the balance chain but as long as you have a tool the chains don't need to be removed to take the pump out

    I have every finger crossed and toes.
    1 and a half grand so far for engine rebuild, 300 on steering rack and still things keep cropping up. Next time advice for anyone, replace engine. Much easier.
    Just brake pads, drop links (a year and 1 month after new) and a good clean left to do. Then gonna see what it's worth as I aint doing this again
