I posted a previous post about stalling and vibrations of my car. After reading the computer, the car gave off the P0306 code. "misfire on cylinder 6". I've changed all boots and spark plugs but still getting the vibration and burning smell. Any new suggestions?

 

Have you changed the coil?

 

First. There is no coil on the 4th Gen. We're coil on plug.

OP ... need more info.

You replaced ALL coil-on-plugs or just #6?

How many miles since ALL coil-on-plugs have been replaced?

 

 

Yes, COIL on plug.
But doesn't that indicate that a coil(s) are indeed present on the 4th gen VQ? Please don't confuse the OP, COILS are indeed present.
I believe AC Max was referring to the coil on the #6 cylinder and was correct in his advice on trouble shooting.

OP -
Move the COIL over to the next cylinder and see if the misfire follows it. If so, replace the COIL. If it doesn't, you could have a faulty fuel injector.

 

1st switch the coil with another one off the front cylinders
then check cylinder 6 for power by unplugging the coil
if no change then check the coil connector for power its supposed to have 12v with the key on if u got power to the connector, if u do have power then get a long flathead screwdriver nd put the flat head side on top of the cyl 6 fuel injector put the handle to your ear and listen for clicking if clicking then lastly just do a compression check

 

Thanks njmaxseltd. Indeed that's all i was refering to. Just a suggestion. middleqy could also pull the COIL on plug up off of the spark plug a little with the engine idleing and listen to weather or not it's arcing and if he can't hear it firing he'd know he has a bad coil and can move on to the injector as you stated.

 

Understood ... I misunderstood what was being described.

 

all my coils are original at 256,000

 

Geezus ... seriously?

I had one crack on one of mine at about 80K and went ahead and replaced them all.

And they were only like $67 each back then.

Now they're like $98 each!

 

lol, yup. guess maxy truly loves me

 

Max ride, just outa curiousity what brand coils do u have do u know off hand?

 

If I'm not mistaken the front 3 are Henshin (check my spelling and pronunciation on that) and the rear 3 are Mitsubishi.

Or, I may have that exactly backwards.

 

I cant remember if u said u bought the max new? if you did, does nissan usually put 2 different brands in them from the factory(back then)
i would think they would all be the same if original?

 

mine are all stock from japan

 

I truly thank you guys for all the responses. I apologize for the delay with getting back to you, work schedule has been pretty hectic. I change all 6 spark plugs and boots but my next task will be to change the actual coil pack on cyl #6. Money has been tight, so spending $100 on a coil pack hasnt been fit in the budget yet. Hopefully that does the trick, Last thing I need is Major Engine work.

 

As a side note, i bought the car with roughly 222, 300 mi ( horrible i know). She now has about 233,500 mi on her. Since trying to fix the issue, Ive only driven local miles on it ( Daughters bus stop and work, which are no more than 10 miles apart) I can tell its getting worse. Im honestly scared to drive it anymore but I have no choice until I gather funds. Any tips in the mean time?

If that's the only code your getting and you've already done the spark plugs the coil should do the trick. Just keep on top of regular maintainence and regular oil changes and you should be fine. High milage doesn't always mean it's bad especially if it was highway driven alot.

 

[QUOTE=ac max 92;8903162] mines everywhere driven and she runs good cause i always check fluids and fix asap when i get any issues. maintenance, gotta maintain maxy.

 

dude , go to the junkyard and get a used oem nissan coil pack...they run about 15 to 20 bux at the yard....dont bother buying an aftermarket coilpack!!!

oem nissan packs are either hanshin or mitsubishi....and will say the brand on the coil pack!! good luck!!

most junk yards have quite A few

 

if your lucky enough to find a maxima with a clean motor, or any motor at all

 

The coil pack was $20 on ebay, it's coming in the mail. I'm hoping this is the solution and not a fuel injector. I've recently ran into a crapload of trouble with the car and the burning is coming from an oil leakage under the hood. Engine was bone dry by the way. Any suggestions on what that may be?

 

Might fix a misfire, but you will get a CEL from that cheap cp.
