As suspected my 2000 Maxima logged a P1320 Ignition Trouble and Misfire codes P0300 and P0306. From what I read in the TSB the P0300-P0306 designate which cylinders misfired but that account for 7 cylinders??? Unless P0300 is generic and 0301 to 0306 are the specific cylinders...can anyone point me in the right direction? Finally... what is the cylinder layout since I dont have my manual with me and will likely need to know which is cylinder 6? Thanks a ton if you can help!

PS-The TSB also suggests looking at the ECCS wiring harness...where is this located.

I recently had a misfiring problem, and the code pulled was P1320. One or more of the ignition coils was bad. 2K was the first year Nissan used the coil system in the maxima, and unfortunately, their design of the coils was flawed. So, instead of issuing of a recall and replacing them with the newly designed coils, they just notified dealers via NTB of the problem. Stock coils will die around 50K. Mine died at 49K.

Since I didn't know which coil or coils was bad, and I've heard that the method to determine this is unreliable, and that the 2k coils were flawed, I just replaced all six myself. To replace them, go to the section in the car manual on how to replace the spark plugs, and do everything it says besides replacing the plugs, unless you want to replace the plugs. It took me about an hour to replace the coils. Hope that helps.

2K was not the first year Nissan used the coil system in the Maxima... in fact, I don't remember when they last used a distributor system (maybe the VG engines in the 3rd gens? )

They've had coil problems, more or less (sounds like they got it right in some years, and screwed up in 2000) ever since they started using NDIS (nissan direct ignition system) back in the 80's.

Yes, replace all six and do it yourself to save on the labor charge. you can get them from Nissan (everyone reccomends DaveB) or can get aftermarket coils from Autozone. Not sure which are better.

My understanding is that the direct ignition with a dedicated coil to each plug has been used at least since 1995. (My 95 max had this set up)Why the problem now when this set up has been used for years is beyond me.

How many miles on your max?

I would LOVE to find any info possible (even if it involves someone donating me a bad coil so I can rip it apart) as to WHY these buggers go bad... or specifically, what part of them goes bad (power transistor, primary winding, secondary winding, or any internal wiring between them)

I'll be happy to donate my dead one to the cause when i get it all straightened out.

Have 39k on my 2000 SE right now.

One of mine died at 132k... I replaced them with a set from Autozone. I will say this however, the set I got from Autozone was IDENTICAL to the set I pulled out of my car. They did not have a Nissan logo on them, but Nissan doesn't actually make the coils. They are stamped made by Hanshin, model MCP-2840 (rear) and MCP-2850 (front), which is exactly what came out of my car! They were stamped part numbers 22448-2Y000 and 22448-2Y005. I don't know if Nissan uses this as their part numbers.

These were purchased as Wells P/N's C1266 and C1267. I put them in anyway because for $300 I can deal with no misfires for 50k (or maybe another 130k?)

I could not find any difference whatsoever. I am interested to hear from anyone who actually bought newer coils from Nissan if they looked any different.

sascuderi

So are you saying the Wells coils from Autozone looked exactly like the bad nissan coils you pulled out of your car?

KCMichaelM

I would say more than "looked exactly like", they were the EXACT same. The only difference was the lack of a Nissan hamburger logo burned into them. However, that doesn't really prove anything yet. I am waiting to hear from anyone who has replaced bad Nissan coils with new/better Nissan coils and can speak to whether the new style look the same (with same part numbers) or not.
