Got a 1320 code after welding my exhaust. Cleared it with my scanner now wait and see. Anyone know a good source to purchase coil if this code comes back?

 

Get coil from a dealer. Any parts store coils do not last. As far as dealers shop around in your area for best price.

I do suggest only buying one coil and swapping it until you find bad coil if and when the code comes back. This way you don't spend a bunch of money replacing all coils.

 

If you want to order on-line, check out nissanpartszone.com.

 

While we're on the topic of welding; I'll be doing a little welding on some rocker panels and lower radiator support pretty soon, what precautions should I take? Unplug battery obviously. I've read unplug ECU. Anything else? Sounds like coils too based on this thread..

 

Ground as close as you can to your work - continue to move/place the ground close to where you work if you're welding long strips.

Have an extinguisher near by.

 

As said before, ground as close as possible to the weld and you will have no issues after disconnecting the battery of course.

 

pretty much what everyone else said and for the love of GOD don't ground the welder on the engine, you can damage several sensors doing this.
