Nissan Specialist :

So, just to verify what you're saying, You had a P1320 and replaced all six ignition coils only to have the P1320 come back. Did you clear the check engine light after the repair?

Customer :

1. dealer and took vehicle in on trade and sent to local service shop for oil change. while enroute the vehicle developed a surging/missing problem. Upon arrival the shop pulled a misfire on cylinder #1 and they subsequently replaced it and cleared the light.

Nissan Specialist :

How many miles does the vehicle have?

Customer :

Then the light came back on with p1320

Nissan Specialist :

They replaced cylinder 1 ignition coil?

Customer :

took to nissan dealer and they said to replace all coils - we did that and the light still came back on

Customer :

yes the first shop did replace #1

Nissan Specialist :

Was the light cleared after the repair?

Nissan Specialist :

Sorry if it seems like a dumb question. Just covering everything.

Customer :

for awhile the light would come on and the vehicle would drive fine - even though the light comes on. the surging/missing seems to be intermittent

Nissan Specialist :

Did you double check your connections at the coils?

Customer :

yes cleared everytime we have tried something. So far all coils have been replaceed. The oil change shop did #1 and I did #2-6

Nissan Specialist :

What's the vehicle's mileage?

Customer :

have not but can. I personally never had a problem with the surging/missing until I replaced the crank sensor but others had said it was doing it prior

Customer :

127K

Nissan Specialist :

OK. P1320 is due to bad ignition coils on your vehicle. A bad crank sensor will give you a different code. You may have a bad connection on one or more of the coils. I have never seen a P1320 on a Pathfinder that wasn't something with the ignition coils. Check your connections and the spark plugs. I recommend Nissan plugs.

Customer :

With this last round of surging it is throwing crank sensor, cam sensor and ignition coil

Customer :

I will double check the coil connections

Nissan Specialist :

Do you still have the old crank sensor?
