Your plug wires are probably just fine, but the cap and rotor do get a lot of wear and tear. You could leave the plug cover off and start the engine at night and see if there is any arcing between the wires and the deep well head.

Inspect the 4 prong plugs carefully. They have been known to lose a prong and destroy an exhaust valve.

When you state 70mph, the miss should happen at any speed so long as the rpm is over 3500 if the problem is the rotor. Putting a 'load' on the engine in top gear could be a compression problem.

Remember, the P030n is a cumulative code, meaning a single misfire will store as pending. Only multiple times on the same cylinder will the code turn on the CEL.
