Check engine light is on, got following code P1320 and P0302.
Changed ignition coil and spark plug on cylinder 2. Still the same problem - car shakes???? and service engine light is on with the same code.
Thx

 

you need to change all of them, because of the bad design by nissan. All coil will go bad. And sometimes the code doesn't show up for other coils.

 

I need to know this for 100% if thats the issue. Not a cheap fix, who do you recomend for parts and if you have instruction on how to change them - pls post. I changed ignition coil and spark plug on cylinder 2 and I only see 2 4 6 ignition coils for cylinders on the top??

Just take off all the coils and replace them instead. Leave the plugs there.

 

Great info, just to make sure cylinder #2 would be under the Nissan cover in the middle???

 

I'm not trying to jump in here if you have the problem solved, but I found that by reading the plugs I was able to isolate the bad ignition coil. I replaced that one coil about 10K miles ago and have not had any bucking since then! In my case it was cylinder #6, the hardest one to reach. What I saw on the plug was more erosion of the electrode compared to the other plugs! Oh yeah, I did replace the plugs at the same time as the coil. So far the other coils are holding up fine!

 

Where is Cylinder 2 located?

 

The cylinders are counted from the driver's side front as one, 2 is middle front, 4 is passenger rear, 6 is driver rear. Hope that helps!

 

You might be fine for a while, but you performance is still no as with revised coils. New coils have silver dot on them. They produce more spark. My coils we failing slowly, one day the worked, one day car started to misfire. After changing all of them I noticed a boost in performance.

As far as where to get new coils, call DAVEB. He sells them for $50 a piece.

 

Um some of the orgers may be giving your false info. My cylinder #2 coil went out like yours and I replaced it. It's on the radiator side of the engine (under the nissan cover) and furthest towards the passenger side of the car. It is NOT the middle coil. If you're standing at the front of the car looking at the engine the cylinders should be like this:

1 3 5
-----------
2 4 6

So I replaced my coil on cyl 2 and the shaking immedialtly went away and the cel turned off in the next few days.
If you replaced the middle coil you probably changed out cyl 4, which is why you still have the problem

 

Yep, I replaced a wrong coil. Changed it today and now all good. Thx
