the sticky tappet wasnt stuck until the engine builder pulled it apart and then put it back together saying it would be fine, but its obviously not!!
oil in it is ok has been since day one
pas is off fiesta and has never caused a problem before
so i reckon its either a dodgy injector or dodgy coil pack gonna use my mates coil pack tomoz so that can be crossed off and the same lad has got a MAF as well so that leaves injectors!
will let you know what i find tomoz!
