I've put a new powerpack on my 97 115 go trying to fix the problem of cylinders dropping after the engine gets warmed up. Didn't work. So I'm thinking new coils next? When we took the powerpack off I noticed the coils had some indentions and hairline tiny cracks on the bottom. There were also scorch marks on the grounding panel between the coils and the powerpack where I guess the coils had heated up. Also noticed that the new Powerpack came with a protective layer to prevent that. Anyone wanna talk me out of buying two new coils?
