FAO Cossietuners, misfire :(
#1
While driving home today in my Sapph 4x4 Cos I played with a ST220 and i felt a tiny/"smooth" misfire at high boost.
However, everytime i booted it the misfire got worse and occured lower down, it got to the point that it almost cuts out when it reach positive boost.
The misfire aint as brutal as the boost limiter or "blown out" spark, its more like its almost cuts out and the comes back on again just to cut out once again. Its pretty much undrivable at boost.
Any ideas what to check? Could it be the plugs anyway?
Car is Sapph 4x4 Cos running stage 3.

Cheers for the help, will go have look right away.
I tried being bufty so i cleaned the panels below and around the coil, also pulled some HT-leads so perhaps i broke something.
Update: looks like Rich could be right about HT-lead to close to MAP-sensor. The clip that holds it togheter with another hose had come loose so its possible for the lead to move closer to the sensor by air drag or accelleration.
