It could be a bad batch of fuel, have you tried another garage or added octane booster to see if there is any difference?

No.. From the box they are set at about 1.0mm. Take them out and set them at 0.7-0.8mm

I brought some PFR6B's off ebay, they all came gapped at exactly 0.7mm. Worth checking though, as if yours are gapped at 1.0mm then that could be the problem as dan says.

Deffo check. The 7B's I bought were gapped at 1mm straight from the box..

Up to you matey. I'd double check them before I went spending sh!te loads of cash when you may not need to. My NGK's were without a doubt set way bigger than 0.7mm. Until you know what the gaps are for definate you may as well p!ss in high winds. What we know so far is that you have change various items and the problem is still there. You need to start ruling things out and you cannot rule out plugs if you have not gapped them. Who knows, you might get lucky.
Up to you matey int it! |

worth checking will do let u know
could knock sensor have anything to do with hesitation |
Next thing to check is the coil packs. Have you had new ones fitted or were they second hand?
Just a thought, was the timing belt changed just before this problem started? |
just to second the coil pack issue..wen you checked them did you try pulling the rubber boots off..i had one which looked fine until i did this and it crumbled away in my hands :cry:
