Yup. Most likely the coil. I would think about replacing everything. Check out Jeg's performance HEI with the polished housing. Low saturation high output coil, performance module, cap & rotor. They have it on sale right now for $100. I just bought pretty much this same one from Eastwood for my '86 K30. They ask $100 regular price but had a 15% off and free shipping that expired last day of November. Might be another coupon out there if you look, though.
