I'm hoping to find some help here with my on going problem. Only had the car for a few months and this problem has always been there, I have so far done the following.
New maf
Cleaned boost solenoid
New plugs (ngks)
Removed dump valve for standard
Smoke tested through induction pipe

Had anyone got an idea of what could be causing this misfire? Anybody had a similar issue that doesn't have anything to do with what I have changed/checked already?

Thanks

Describe the misfire

feel more like a hesitation, only happens on WOT if i am progressive with the throttle it isnt so bad BUT it does still hesitate.

I had a misfire on boost just after having it mapped ...turned out to be my plugs so brought NGK7B's problem sorted ..

ive just checked my reciepts i had for the car, the plugs were changed just before i brought the car... guess what, there not ngks as i was told.... bosch super plus FR6KPP.... anyone ever had these fitted/
car is prodrive "mapped" aswell i forgot to add.

mine was an air leak on the inlet pipe, hard to see but the joint was cracked, once that was fixed it was fine then a different hesitation occured, that was a coil pack that needed replacing

havent you fit NGK`s ?
Id check the gap of the plugs

Bugz_wm

no i was told that ngk's had been. think that will be my next change then, just to confirm the gaps should be 0.6-0.7 yes?
