hey, another misfire thread I know, just thought ide try to get to bottom of it while im at work.

started car this morn, started fine, drove out, no probs, car got warm so boosted slightly, hit 0.5, and it stuttered and im pretty sure spat out a big flame, popped banged the lot., so dropped boost back down, no problems, stopped the car few minutes later when got to the station, and it just seems to lightly miss on idle, if I even put the slightest bit of throttle on it stops missing.

wha the fuuuck? its had a new coilpack bout 6 months ago, runs blitz 9.0mm leads and ngk bkr7eix plugs. I think it may be the leads, but i dont want it to be because there fairly rare and i like em haha

mine worked on idle and low power output but when u increased boost pressure it became too hard for a worn plug to spark

mine did this when the vac pipe to map sensor came off, its located at the back over the engine below the strut brace!

I changed the plugs and all seemed fine, until this morning! it happened again, gay, but it doesnt miss on idle, it just misses past about 0.5 bar, any ideas? im going on holiday for a week this afternoon so will be investigating when i get home
