Could be, but more than likely it is going overly rich at that point and that is what is causing the misfire.

Ed, since you have said that your car has over 500hp, I assume that it has a onboard air-to-fuel meter . . . if so, what AFR is showing when it misses (probably in the mid to lower nines). I also have to assume that the K-Jetronic fuel system has been replaced with some form of EFI - do you know what type is in there?
