[Engine] rattling injector ?

[brodfather11]

Hi all,
          After having refuelled at a supermarket with diesel a rattling started.  It sounds like an old petrol engine with a worn timing chain and a tin of ball bearings being rattled along with an old sewing machine at full pelt and power was down .   First though was I filled with petrol instead of diesel but checking the receipt , no it was diesel.
 It did not not rattle at idle , its normally quite quiet for a 1.9d,  and it kept going  but heavy on fuel , no black smoke that I noticed.

It did this  for 15/20 miles then when got home and switched off and started it again when cooled down. No noise and power back to normal .

I think it may be  a sticking injector , normally use redex diesel cleaner but skipped last time as I had none left.  
 It makes me think it may not have been the injectors as skipping redex once or twice shouldn't be a big deal.  

 Any thoughts ? something else maybe EGR valve or what ? ,

PS  I see 4 injectors, brand new for £65.00 on fleabay , has anyone tried them ?

Is one loose..?

Try some millers. Sticking injectors usually stay that way, mabe just an odd thing happened, see how it goes.

Still looking at things but there are no loose injectors

Try using a large screwdriver or a piece of wood held onto the engine as a stethoscope to locate knocking noises..

If it were me I'd check there was no water in the fuel filter - is there a drain screw on the filter ?

Given that all now appears ok with both noise and power I'd leave things alone for the time being otherwise you could end up doing a lot of work and spending a fortune chasing all the X Y and Z suggestions that may crop up - no offence meant to anyone of course !

I'm waiting for it to appear again, will check for water but new filter a month ago but that's not to say the fuel I put in didn't have water in it . ( expensive water at 133.9p per litre )
