Anyone know where to get Allison coils? They may be Crane now, don't really know. I'm running a 1st gen 13b in ITS and these were in it when I bought the car. I'm having trouble after everything is up to temp and under load. A lot of hesitation and missing under acceleration. I switched the leading and trailing coil in between races(at Waterford Hills) last weekend, seem to clear up for Saturday class race but problem got worse at Sunday feature race.I'll be the first to admit I'm no mechanic. Any suggestions?
