Well you probably need plugs for sure at 200K so a good place to start if they were not done at the 100,000 miles. I have heard that the newer units are improved and since these are coil on plug units (you have to remove the coils to get the plugs) you can check to see if they are the updated coils...I have heard the markings are different. If you are having the dealer do the plugs be prepared to spend some dough anyway since they are costly in parts and labor to replace. Check the codes too...find out what banks are throwing a code and check the plugs on those to see if they look noticibly bad...Can you find out through the dealer any service records using the VIN? Good luck...my truck runs like a champ for sure.

Sorry...didn't see any PM...and I haven't been real diligent about checking...so the answer is YES...the truck has run flawless since this. Keep in mind I bit the bullet and replaced all 6 of them...I could have just replaced the ones that threw a code but since I purhased this truck for the long haul I wanted the peace of mind. The truck only had 46K on it...and now that I have closer to 58 on it..the one thing I wished I would have done since these are coil on plugs was to do the plugs at the same time...my mechanic said it wasn't necessary since they are 100K plugs but I prefer the preventitive approach...still though I didn't do it and now wished I would have! Still though the truck runs great so probably not neccessary. If you have higher miles you might do it at the same time, all depends on your budget. Oh if you do it....go with the OEM NKG is what I hear. Sorry for the delay on the post! peter

hey these are great, I am hesitant to make an offer as fear for lowball...Mostly the combo to ship them to 60604 might make them less appealing...I'd prefer if you let me know what you'd like for them and I'll let you know right away if they are not already sold. If you do decide to put them on the Bay, I'd bid on em...THANKS! Pete ptirone@j-quin.com

I can add this to the forum. I just had all 6 of mine changed as I was getting mis-fire on both banks. I have a local garage and the cost for him to do it vs. me was the difference in his labor (about 1.5 hours, in which he also cleaned the MAF and throttle body). The truck runs fantastic, and here's the odd thing...I was having some concern about that harsh or seemingly mis shift between 1st and 2nd gear and since the new coils were installed it's all but vansihed which is GREAT but I don't understand why unless that engine misfire was also creating some issues with the shifting pattern? peter

Let me know where you are located (the color) and $$...I may be interested if shipping or location does not warrent expense. You can PM me at: ptirone@j-quin.com THANKS!

Hello, I have at least ONE OEM (silver) factory step rail getting some rust thru. Any opiniouns on what to go with for replacement of either finding a USED good one or just bagging both of them for a new set? I like the stock set up and look as well as the ones that are found on the LE's. Need em for my tikes and Mother in law. No off roading for me anymore for awhile. Thanks!

Greyscale, While I can't explain the low levels of power at your lights, I drove a 94 SEV6 with a MANUAL trans and over 140K I had to replace the clutch Inerlock relay 2x and one time had really nasty/dirty connection to the starter that was causing some problems. Not sure if your truck is a manual or not...sounds more like you have a battery cable problem though. Peter

$750.00 later I have 6 new coils, a cleaned MAF and throttle body. 12 month warrenty on the parts so here's hopes to a trouble free 50K. Apparently the new coils are corrected for whatever defect they had. If it were not 14 degrees here I may have opted to to this myself would have saves about $200.00 but it's done. Thanks everyone for the insight. Peter

I have 2 bad coils one on each bank...My local mechanic (that I trust) says that while it's up to me the new coil packs are redesigned to resolve this issue...so I could replace 2 or do all 6 for about the same labor just extra parts. I just bought this truck about 4,000 miles ago for under $10.5 with 44K on it and so far put a new battery (preventative) set of new tires (again my choice)..so I figure I'll invest in the coils and they have a 12 month warrenty so here goes. I wonder if I should have gone with a newer model 05/06 used but I do like this style better and the interior quality is nicer (to me). Here I am selling myself on if I made the right choice! SO, without further whining...I'll throw some additonal $$ at it and see if anything else goes on.

I sprayed mine down with silicone spray (has some from the Yamaha shop) worked like charm...they are still slow in real cold weather but at least they work. Pete

I was told by a nissan tech that about that rpm is where (and i apologize for lack of memory here) two sensors switch over and that cycling is normal. Then he asked me why I would hold my rpm there...well being stuck in traffic and bored trying to find out what was going on with my now seemingly real issue with a coil or some other electrical demon. I will post a follow up. Pete

Well there you have it...I knew something was brewing. Started, was stumbling...I opted to drive it to hopefully draw a code...I got a flashing SES light, then that went out, then back on with soild lit SES...will see what she says. Peter

THANKS everyone, nice to see such an active and friendly group. Great Idea I need to take pics...nothing out of the ordinary, silver, black leather seats, Giant OEM pushbar. Frankly this is a luxury car compared to my 97 XE (RIP). I got t-boned by someone running a red light at about 35 MPH, hit right between the drivers door with the front drive system taking most of the impact. No airbag deployment and the darn thing was still running and was drivable but bent up pretty good (although leaking coolent). Anyway long story short, found this one very clean, more power, simple nice features, LEATHER and sadley with a few recent nagging issues (I like things to run perfectly) but hope to have it ironed out soon. Friday I am going to give it a throttle body cleaning, change the plugs and check the wires. From there I can at least rule those items out..and the plugs should tell a story if indeed only one is misfiring. I like the Pathfinders quite a bit as you all know! Pete

OOPS~~~ 2001 SE 48,000 miles

Well, I just joined today and am already posting a question for help..I think I've read every post on several possible issues but here is what I have... I had replaced an 02 sensor several weeks ago...about a week later I started the car which began to shudder, I gassed it a bit...it ran OK then I shut it off and restarted been OK since...BUT I feel like the car is lower in power and I have a slight hesitation when I am crusing and hit the gas, almost a stumble. Then while sitting in traffic I start to experiment and discover that ONLY between 1500 and 1800 RPM the engine cuts off for about a millisecond on and off cycling. I have not had any codes present....the Auto Zone guy checks and sees that the scanner is showing engine misfires...but again no specific code... Is this a coil going, bad plug, bad wire???? My local Mechanic says to wait till i get a code to isolate the issue...I would think the misfire alone repeating would toss a code? Thanks for any thoughts on this!
