Ok, I got a cylinder number 2 misfire and plan on replacing the coil for it. My questions are:

A. There seemed to be a level of uncertainty among the dealers i called on which was cylinder number 2. I think it's the one closest to the belts on the back side of the engie (towards passenger compartment). If this is correct.

B. How difficult is it to replace the coil all the way back there. What is involved?

Thanks for any insight

 

The coils are very easy to replace. You unplug it, take out the two screws and put in the new one. Cylinder number two is (facing the engine from the front of the vehicle) the closest one to you, on the left. They go in order like this:
1 3 5 <-- back side of engine near the firewall

2 4 6 <-- front side of engine near radiator

 

Wow if a dealer doesnt know right off hand which cylinder is number 2 then my car is definately not going there

 

Please dont think that I'm disagreeing, because you're the first person i've heard not append "i think it's" to where they say and that makes me feel waaay better.
But, can anyone either confirm or deny that this is correct, i need to feel absolutely confident when i get the coil from the dealership I can tell them where cylinder 2 is since they dont seem to know. (this is after calling 3 different dealerships service departements in the city)

 

MAXINXS is perfectly correct. Check your owners manual in the specifications section.

Cheers

 

awesome, thanks guys we'll see how it goes

 

The dealer doesn't know which is #2 cylinder? Another moron working for Nissan

 

On my car I replaced (myself) the coils as they failed. All three at the front of the engine failed, all three at the back have been fine. Has this been others experience? if so, maybe the thing to do is just replace the three front coils with the grey dot ones and avoid future aggravation...

 

Damn that is pathetic on nissans part. Any person who can pick up the user manual that comes with the car should be able to figure out which one is #2.

Replacing the coils are easy. You need a hex key to undo the 4 screws holding the front cover. After that will see 3 black things underneath. These are the coils. Just unlug #2, and there is a single screw holding the coil in place. Just get a socket wrench and remove it. After the screw is out, just wiggle it and pull up. it should just pop right out without too much effort.

 

How did you know that the front 3 coils failed?

 

How does more than one coil go at one time? I remember when I had one coil go. The car knocked like hell at low RPMs and the SES light flashed at start-up a first then stayed on constant.

 

They failed over a year and a half. The MIL light would come on, and I would get code P1320 on my tester (bad coil).

I bought one front coil, and one rear (because they're expensive!) and kept switching and resetting MIL until problem went away. Each time is was a coil at the front end of the car. Now all three are replaced with 'gray dot' ones and no more trouble.
