Instead of throwing a bunch of parts at it, how about diagnosing it or having someone with the tools and knowledge diagnose it.
P1351 is a difficult code to diagnose if it is intermittent. You really need a lab scope to diagnose this problem.
Basically, the PCM is seeing an open circuit in the ignition control circuit. The PCM controls the ignition coils directly through the IC circuit once a transistor inside the ignition module is commanded to turn on by the PCM through the bypass circuit.
Need to have someone with a lab scope to monitor the 5 volt bypass signal to the module and to monitor the IC control signal. With that information, they should be able to isolate the problem.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.

When you get a free diagnosis, you're getting exactly what you paid for.
Real technicians can't diagnose for free.
