Hi All, sometime back I asked about a miss fire I had under boost. Last night I finally fixed it. And as I said I would report back when I fixed it, here it is.

 

As the engine twists slightly under hard acceleration the connectors onto 1 or 2 of the coilpacks were being slightly pulled apart from the coilpacks.

 

I knew my clips were duff, but as they seemed to sit nicely I thought they would be OK. And everytime I checked they were sat properly onto the coils. Wrong.

 

I have made some ropey looking brackets that use one of the bolts from the coils to secure them, these clips hold the connectors onto the coils.

 

Result, my car has never run better. I can now buy new connectors.....And think of all the time I have wasted when I really should have known better.

top banana ...........one for the memory banks that one..!! cheers Mark

Just goes to show how much time and money you spend on something as minor as that :(

bet you feel so releaved now though :D

Had same issue and fixed it, then missfired again only this time it was the injector clips on 5-6 cyl, fixed that and never missfired again.

Very happy, car goes really well now...

good to see the finished answer from a problem

nice one mate

And I even washed it today to celebrate, lol.
