Code P1320

My 2001 LE just came up with a code of P1320. The engine has "shuttered" very briefly every so often (week or two) over the last 6 months but no code until now.

Any thoughts,

you need ign coils. You can try doing one at a time but, will most likely end up buying all 6 to get the light off. If you have a spec. cylinder misfire, replace that coil. I have tried to save customers money before on these but, usually end up having to replace all 6 coils.

With 88k on the car, it being in great shape and my having the intention of keeping it for a long time to come should I just replace all the coils while they're in there. Along those lines should I replace the plugs at the same time too?

I have a 1999 Nissan Maxima that has failed inspection twice because the engine light stays on. First, I had code P0325 and I replaced the knock sensors; now I have a P1320code and I just replaced the camshaft position sensor. Unfortunately, the engine light is still on. It went out after the mechanic put the sensor in, but when I started it up and begin driving, the engine light came back on. What could be the problem with this now?

P1320 codes are most often set by an ignition coil failure on VQ-series engines. If you are lucky, it will also show a P0301-P0306 code, or codes, to identify the cylinder on which the coil is failing. Hanshin made coils or more likely to fail than the Mitsubushi made units. If you don't have a cylinder misfire code, it can make it difficult to identify. Many simply replace all 6 coils, which can get expensive at roughly $75 each. When I worked for Nissan, tech support would suggest replacing one bank of coils and see what happens; if the code came back, one would replace the other bank. At least that way there's a 50/50 chance that you'll only have to replace 3 coils instead of 6. You can do a resistance check on each coil, but those tests don't always confirm a bad coil. Often these coils need to get hot before they fail.
