P1320 code and P0301 for some time. Problem was intermittent at first and difficult to isolate. Sometimes trouble starting. Sometimes hard idle but RPMs don't vary. Sometimes feels like a lack of power with acceleration on interstate. Replaced coil #1 and all spark plugs. Fixed the starting issue but nothing else. Took it to dealership for diagnostics. They said coil #2 was bad. Now the miss seems almost constant, no power at interstate speeds. Replaced coil #2 and cleared codes. Still with miss and codes came right back. Disconnected each coil one at a time to see which one might be bad, but heard the engine slow with all six. Any other ideas or suggestions would be appreciated.

2001 QX4. No I did not use dealer parts but they did say OEM. If I knew how to fix the P1320 1st I would. I'm stuck right now with this light on.

Other than the ignition coils, I haven't seen any other component triggering the P1320 code. The only way to be sure is by connecting an oscilloscope to the coils and check the voltage.
