I dont bloody believe it this misfire is back,

Cold misfire as normal but now on high boost,

To reiterate,

Cold start fine fast idle comes off misfire starts to happen, and now high boost miss 1.3 @ 5, 000 wot

Afrs are normal 10.8 -11.3

Error 14 as normal, plugs are new well changed last time and fixed the miss but they look like new

 

Starting to think it could be the igniter anyone local to dartford got a tt I can try there igniter out

i changed the ignitor and still had the same problem

 

it then got so bad i could not drive on boost at all swapped back to the old original coil packs and has been good as gold since

I believe it was a combination of coil pack and coil pack wiring issue

nightmare lol.
