Hi all,

I know its the crimbo period, but I was driving back from Devon today when the car developed a miss on boost, and eventually all the time. I am hoping it is just the spark plugs, so my question is what would people recommend??

Ive got a v3 sti, running ecu and bits tuned to 320ish.

Thank you

coil pack if you need any i have two good ones take them off and check for cracks under the rubber seals sound like you have a cracked one

That was my first thought also.

Plug type/ temp depends on state of tune. The higher the tune generally the higher the engine temp so a different temp plug needed for self cleaning.

Ah, that could be a bit more of an issue then. Sure ive got big coil on top of block?? Or does each plug still have coil pack on. My 95 wrx had individuals, thought the facelift had the one
