I have search the forum and haven't really found anything that anyone has tried that worked. 1996 infiniti I30. I am getting the p0303 &p1320 codes. I did pull #3 coil pack and it had a crack on the extension so I assumed the spark was leaking out. Replaced the coil pack along with all spark plugs. #3 plug was wet when pulled out. I have verified that all coil packs have voltage and have visually inspected the wiring & connectors and all looks good. Still getting the codes. I am a pre ECM mechanic so my trouble shooting with these ignition systems is a little limited. Hate to just start throwing parts at it. The car was taken car of and had regular service thru out its life
