SR20DET Miss Fire\Bucking

Hey Guys, looking for some opinions as these things are always hard to troubleshoot over the interbutts.

91 240sx\SR20 Blacktop Swap

Issue: Car bucks\misses after warming up at highway speeds. Feels like a misfire, although happens really sporadically.

Troubleshooting thus far:

TPS Reset - Good
New Fuel Filter - Good
New Spark Plugs - Good
Throttle Body\IACV Cleaned - Good
New Walbro 255 Fuel Pump - Good
Vacuum leaks - None detectable at this point, will continue to look.
Repinned CAS sensor wiring and replaced harness side plug - Good

I suspect at this point Cam Angle Sensor faulty or Igniter Faulty.

Anyone have any ideas? Things to check?
