HELP - P1320 Code

I have a 2000 Nissan Maxima and my SES light came on 2 weeks ago. I went to Autozone and got the code P1320. I have called Nissan and did many searches online and found most people had a problem with their ignition coil. I did a check on Saturday and none of them were bad, or at least the OHM's were reading good. So I decided to change each spark plug, just in case there was a mis-fire and I also put in Gas Treatment when I filled up the tank in case there was something in the fuel line but the problem still exists. Besides the light being on my car shakes when I am stopped and shakes at very low speeds but sounds like it is going to back fire, plus I have no power at all when I push the pedal and it takes a bit to get going.

Can anyone help with this problem or tell me what I should try next? I do not have much money and cannot really keep taking it is to get checked or to fix things that do not need to be fixed.

Seems that one or more coilpacks bad. Seek the forum, recently similar threads.

The only way is to get one good coilpack and start swapping. When u replace one, and get better response, you've found one source. Hopefully thats the only one. Some say that lowest price may be around 50$, dunno. Ask Junkyards...but theyre things that are always baked dead, better have new. Rear/Front rows have different lenght coilpacks; test might be possible with extension.

Maximas [as many other cars] have been manufactured to be rollin goldmines for stealer$hip spareshops: if low on money, either DIY or buy basic high volume [lots sold] vehicles like Stanza.
