p0304 and rough idle
just bought an 03 disco. 120k miles for $2500. flashing engine light with p0304 engine code. grounded plug to check for spark and saw none. assuming that the wire isn't on the coil properly. have spent a few hours reading this forum to determine best way forward. 7mm wires on it now. 8mm ordered this morning. best to wait and replace all?

Sometimes plugs go bad and can put strain on the wire and/or the coil.
