Less than a month ago, treated my 96 to new plugs and a coil pack set. I got this code even though the car isn't misfiring. Could the computer be throwing erroneous codes to make me dump more cash into it?

 

Ignition signal primary? Some days, I would much rather be driving the 83 Dodge D 150 that I used to have. Infinitely easier to work on.

 

Are these OEM coil packs or aftermarket?

 

Came from Amazon

 

Contacted the seller of Amazon, see if they will replace.

 

OEM or bust on coilpacks. Aftermarket packs throw a P1320, this has been said for quite some time

 

Don't have $600 for OEM, at least they aren't misfiring like the original ones. Does 1320 make the car run like crap? Replaced first o2 sensor 2 weeks ago, now bad. Granted timing was way off due to a bad camshaft position sensor which I just changed.

 

Pull OEM coil packs at the JY or post a WTB in the 4th GEN classifieds. I got 6 used fully functional OEM coil packs from another member 4 years ago for $60 total.

EDIT: The aftermarket ebay coil packs I tried before that threw the P1320 code within 2 weeks.

 

Get used OEM coils. Code is gone.

 

Okay, contacted the seller, they are going to try to fix it. Is it a calamity if the coil pack comes off the boot.

 

As long as you are using aftermarket coils, you will always have that code. If your existing coils are OEM and you have a misfire due to them, get a used set of OEM rear ones and leave the front alone.

 

Found the problem, one of the coil packs wasn't entirely plugged in. Code is gone

 

Please post your continuing results with those coil packs...i have 105k on my 98 gle and would like to know what brand you got from amazon and how they continue to work....for future possible needs....
thanks

 

Right now, I have ignition signal primary even though all the coil packs are tight now and misfire in #4. Tried using some of the hanshin packs that were in there before. No dice.

 

#IC47 95-99 Nissan ignition coil. 222483IU06 $91.50 + $7.49 shipping, you might have better luck than me

 

$35 coil from rockauto is working fine for me after a month

 

Could misfire code be a spark plug? It looks okay, but wasn't firing for a few weeks because I didn't think of checking coil pack connections. As a result, a lot of unburned gas went through it. Did clean it, but not sure if that was enough

 

Primary circuit fault code is gone after putting in one of my old hanshin coils.

I bought these because the description said "Hanshin", what I didn't catch is that it said "Hanshin-style" coil packs.
As soon as they came in I took one look through the plastic bag and saw "Made in China" and sent 'em back, ordered the OEM through a dealer online for around $90 each, not worth risking a code and poor performance to save a few dollars when these are one thing that will leave you stranded in a heartbeat if they are not up to snuff.

 

After market coils usually have the wrong resistance value built into the primary winding, causing a DTC. This is a well documented issue, buy new or used OEM.

 

Could a spark plug cause misfire if it is two months old or did I put in a bad hanshin?

 

Most spark plugs will easily last 50k miles, highly unlikely that it is bad unless the tip is not gapped properly or the ceramic is broken, more likely that the coil is the issue at hand.

 

Thank you much do have more coil packs, does it hurt to use the back set? The screw holes don't quite fit do I wondered.

 

Bank 1 (firewall) coil packs are different front bank 2 (radiator) coil packs and cannot be swapped.

 

I only have one the rest are oe

 

I have 5 Autozone paks in my 99 over a year and never got any codes. Used OEM can be hard to find especially in a pinch. IMO OEM new are overpriced. To this day Nissan is making a fortune on their own prone to failure design.
If this generation Max has an Achilles heel, this is it.

 

Prone to failure design??? The only Achilles heel for the 4th gen is the lower radiator support. Seeing that I had a 95, the OEM coils were made from Mitsubishi and I can say it lasted just under 300K before I had to switch to Hanshins...

 

Everyone from the junkyards to the aftermarket to the dealerships is well aware of the Nissan Maxima and its coil pak "issues".

 

I havent had any issues on my 96. 16 years old and still going doesnt sound failure prone to me.

 

Found a hanshin that was floating in my trunk . No more misfire. I replaced all of them because I was getting random multiple misfires. It is a front one engine cover is back on minus one bolt. Credit card got hacked so I can't replace both oxygen sensors so my car would be code free.

 

My buddy found a full set at the junkyard still original. Now I'm carrying them around in my trunk

 

95-98 coils are good
99 coils are junk


I see that you list yours as a 99, hence your coil troubles. My 96 had no issues with coils (in 2 years), my 99 has had constant coil issues

 

Going to hit a yard. #4 keeps misfiring. Out seems fine on first puddle, upon acceleration, you can hear the skip. I'm playing musical coil packs with the old ones i have. Boss is gonna love me calling in late for this.

 

A word of advice on the autozone duralast coils . . . I replaced one about 4 months ago with duralast. It worked for a few months. Then started misfiring again. Tried two different duralast coil packs. Neither worked.

Went to JY and pulled two hanshins. Paid a total of $15. Worked like a charm.

The packs I pulled were of a 97 with 190k miles. But that made them 100k miles newer than the ones on my 96!

 

Of course this assume that the OP put in the OEM platinums or maybe iridiums....if they used copper then the plugs would be done after 30K miles.
