So now after the replacement of the UIM, LIM, and valve cover gaskets replacement the car is throwing this code for random misfires. I pulled the coils and they are really old looking and faded so I'm guessing they've never been replaced.

So should I just save myself the headache and replace all 6 coils? I found some beck/arnley ones on rockauto for about $330 shipped to my door, also some on ebay for $175 shipped (but I don't think ebay is such a good idea for ignition coils)

What you guys think?

 

Anyone chime in please.

 

How many miles on the car --- I would spend the $300 and get OEM from Dave Brunette?

 

187k

 

im getting the code p0301, it says on my code reader cylinder misfire 1, by replacing coil 1 alone will i fix this problem?

 

i got some used ones for my rear...(3 total) replaced it...my car hasnt skipped since *knock on wood* you could get used ones, but i highly recommend if you buy new, go to the dealer. which cylinder is misfiring. i know its either 1,3, or 5

 

It just has the p0300 code for random misfire slim, it doesn't state which one.

 

have you cleared the code? if not clear it and see what pops back up..or you could just wait until it becomes more obvious via code which one it is. its usually teh rear ones that go bad though. did you do your plugs?

 

maxima king, search p0300 , the guy gives a good write uup on how to find which cylinder or cylinder is misfiring...

 

Yea I cleared it the day before yesterday, I'll read the codes later and see what comes up and report back.

 

Code hasn't came back yet, so I'm just going to leave it be for now until it comes back I guess.

 

187K is huge really huge, I replaced mine @ 60K miles, thx to buggy 2000 coils. Wonder how urs lasted long long.

Go get yourself a 6 pack (OEM only) and new plugs (NGK) and give a new life to your engine.. trust me a great investment.

U will recover the $350 over a yr in MPG savings..

 

I have new ngk plugs in and I have no idea if the previous owner changed the coils since the ones in the car are all grey dot I'm assuming they must have been changed since I just read that the no dots were the original faulty ones.

 

Btw 187k isnt anything, baby miles

 

i have to agree, i did get better gas mileage...i'm now doing about 24-25mpg mixed/city driving and i did about 27 mpg on highway...better than the 22mpg mixed/city and 24mpg highway i was getting...

i now average at least 400 miles to a tank...not to mention i found a spot with non ethanol premium gas....W00T

 

how would i clear the code???

 

Once P0300 starts there will be an imminent coil failure pointing to the right coil P030x soon. But in the case of the OP he has a lot of miles on his coils -- piece meal replacement based on the coild code is shortsighted and opportunistic.

I would replace all and move on...

 

you clear the code by using a OBD code scanner...you read what code you have and you have teh option to clear the codes. go to advance or autozone and have them do it

 

thanks i have a scanner but just got it and im still a noob, will try

 

Car already has new plugs ngk iridiums, and I have another set of the same plugs so should I still replace the plugs after I replace the coils?

 

no....start replacing coils

 

Ok I'm going to call DaveB tomorrow and order them even though the code never came back I'm going to replace them because I like everything to be fresh

 

must be a baller lol. coils too expensive for me to replace all of them when some were good.

 

No not a baller at all but I never just replace one of anything I always replace all, plus I got the car for a low price so I can afford some of the extras. Btw how much are they going to run me? I've been told $350 or so or did someone send me off?

 

the parts store has them for about 70/coil at least...so just say about 90/coil from the dealer....$540

 

$350 for OEM coils is a great price. Around 400 is the best I can find online...

 

$540 Maybe I'll replace the 3 rear now and the 3 front later on.

 

You are right... I got one coil from DaveB for $90 last year becoz the yen has risen against the worthless dollar (79 yen/$).

 

I had same code last year. Replaced rear 3 coils and haven't had a code for coils/misfire since. I replaced other 3 following month to be safe. If one is starting to go the rest can't be far behind. Just my .02

 

Well its been 3 days and the car hasn't thrown that code instead it threw the P1440 code for a small evap leak today WTF!!!

 

its usually the rear coils that go bad first anyway..think about the heat that those coils are exposed to...but i've only replaced one coilpack (same cylinder i mean) since i've had the car, almost no need to replace the front....NOW you say why i called you a baller LOL

 

Baller my *** bro haha I can't afford that **** right now

 

thats what i said

 

Just ordered all 6 coils off ebay they are the same as OE the Hashin ones same part number and all even call Nissan to Verify the part # and the brand so it is possible to find exact OEM piece for a very good price....

 

Got a link for us Rod?

 

Will put it when I get home, right now at work using cell phone will have to check also for the 00-01 since mine is 03 even seen them at 1A auto.com and they had a 6 pack for under 150 buck think they were out of stock though for your year but will check if the guy I got them off ebay has that year since mine from the dealer they wanted 150 each coil......

 

Damn trying to find the link where I ordered but doesnt pop up it was from Alaisdeals, cause he only had 2 left when I ordered and for the 00-01 when search they dont pop up....here is one if you want to try they say 100% money back guarantee and has a 6 pack also but you should try one if skeptical since everybody always bags on ebay but goes on it and it all comes from Japan or China anyway,here it is, http://cgi.ebay.com/ebaymotors/2000-...mZ320664653869 so good luck on whatever you decide the 330 from Rockauto aint that bad if you want those.......but here is the Alaisdeals # if you want to try 1-909-724-4397 8am -3pm monday - friday sat I think till 2 pm pacific time...I know this **** is long...

 

Thanks a lot man definitely appreciate it! Only question I have is what brand is OEM since they all use the same part number even aftermarket so it doesn't do any good to look for them by part number.

 

Not sure just hit up Nissan a Sec. ago and they said it doesnt say so who knows just gave the part # 22448-2y005 for front and 22448-2y000 for the rears but when I called for the 02-03 they said Hashin, so dont know what to tell you...maybe they are the same as Ebay nobody knows....

 

Who knows haha I don't know which ones to get now and my car hasn't thrown the code again so I'm just going to wait now.
