My 99 max misfires after its warmed up a bit. I tested the coils with a cheap multimeter and here is what I got.

Misfire has been going on since i've had the car for a year or two. First time I brought to it my mechanic he said it was a coil pack and replaced one of them. I don't know which one it was for sure but 1 looks the newest and also a number on top of it (05053) which the others don't. I'm thinking this probably isn't an oem replacement?

How I numbered the cylinders, if you are facing the front of the car.
456
123

1: 0.88 ** Looks the newest, replacement?
2: 1.48
3: 1.44
4. 1.48
5: 1.48
6: 1.40

Pack 1 is the only one that really stands out. Other than that they all seem to be roughly the same. How about 6?

No SES light on now but there is a pending p1320. I should also mention that I tested the coils when the engine is cold even though the issue only seems to occur after its been warmed up for a while. I remember a user on here talking about false negatives when cold since the insulation only begins to fail after its been warmed up a bit. I'm also replacing the plugs. I only checked the front 3 cylinders today but discovered that 1 was an NGK platinum and the other 2 were bosch platinum.

 

Our cars like ngk. They do not like Bosche.

 

The ohms of the replacement injector do appear to differ considerably from the others.

Other members might offer more specific advice soon.

 

A coil from another manufacturer could have a different resistance reading from the factory Nissan coils (which I think are Hitachi) and still work OK.

But if it is causing a problem, I would think you would get a P030x (P0302 in reality) code since you only have one coil like this.

FWIW, bank 1 of the engine with cylinders 1 3 5 is by the firewall.
Bank 2 of the engine with cylinders 2 4 6 is by the radiator.

 

I just check some coils i had in the closet...all good coils and got anywhere from 1.50 to 1.61...all of them are hanshin coils....4 rear and 1 front coil...

 

I had a random misfire that was annoying and never threw a code and one time caused me to have to pull over at highway speeds because it was that bad. swapped coils from a parts max I have seemed to be better but then it happened again. Turned out it was the MAF causing it. Swapped it out and has been good for 3 years now maybe 4. So not always does it throw a check engine light or be a coil pack. I am just going from my experience if it helps.
