So sick of these skylines and there shitty coilpacks. Yesterday i did a full service, basically changed the spark plugs, oil and oil filter. But when i was test driving the car, you could hear it misfiring. The cylinder seems like its still running, its just not getting a 100% proper connection. Basically you can hear the exhaust pop during idle, and as your taking off it slightly misses and when you flat out give it, it chugs back every 1000rpm or so. I checked the coilpack loom connections and made sure they were all plugged in...so does it seems like its one coilpack thats basically failed? its a f**king rb25 neo n/a so to unplug coilpack 2,3 and 4 you need to take off the god damn plenum extension and a few lines on top of it!

Depends on the people that own the car before you to. My Skyline was imported by a family member who lives in Japan and it has genuine low mileage, and completely stock, the only issues I've had are headlight switch and the window switch. Not bad for a car 1/4 of a century old!

When you changed your plugs did you adjust the gap correctly and use the right plugs?

Did you check the coil packs for arcing and tape them up if you saw some?

Did you use dielectric grease around the boots before you put the coils in?

Is the coil pack loom OK?

Im just gonna change all the coilpacks and loom because they are all pretty worn out and damaged the coilpacks already have tape on them and some of the inlets on the plugs are broken. Do you think its still ok to drive the car for a few days? it wont damage the engine or anything like that?

no it wont hurt it too much if it's only missing

ok cool thanks. Like i said it misses every 2-3 seconds on idle and when you plant your foot down but doesnt miss when you are cruising it. Also, i really dont want to pay that much for yellow jackets, if i had a gtr then i would be more than happy to but its just a n/a so ill get stock coilpacks

Guys i need your help. I changed the coilpacks and loom and it still didnt fix the issue so it must be spark plug issue. But ive always used the same spark plugs - ngk bcpr7es -11 . I know its a bit over the top but it always ran good with them. Im left with no choice but to gap them to 0.8. So you think this will fix the issue? It took me like 4 hours and alot of sweat and blood to pull everything apart and put it back together so im pretty pissed off. I didn't even go work today to do it so i lost out on alot of money anyway. Please tell me this will fix the issue otherwise i got no idea what it would be. I also used 10-40 penrite fully synthetic pro racing esther.

If i gap them to 0.8 and it still doesnt fix the issue, then what else could it be? This shit is giving me anxiety i want my car running properly otherwise its always in the back of my mind

Thanks

    • Just wanted to pop in an update on my setup. The CD swap has been great, I love the mazworks housing for the overall simplicity. I ended up sealing my trans tunnel with a thin sheet of aluminum reused some of the holes on the trans tunnel, and laid some window sealing EPS foam around the edges. Works great, really quieted things down and sealed up the car.  As for the power comment. Right now I am also running about 650whp. with the way the bell housing is attached to the face of the transmission I have zero doubts it would be fine, mainly because the input shaft and main shaft bearings are seated into the bell housing adapter. This means the load is NOT on the bolts to maintain the power, rather into he casing of the bell housing; Yes the bolts are doing some work there, but with both shafts locked in zero worries.  End of the day, the Mazworks solution is the easiest and safest. no need to take your trans to a shop to get milled perfectly, it fits with minimal clearancing, and you can use all your existing clutch and flywheel.  Driving wise the CD has been great compared to the big box, I'll probably swap my final drive at some point. The serial 9 shifter is gooooood, my only qualm is how tight it is, it takes a fair bit to get use to, 5th and 6th are a bit eh/hard to find at times, but maybe I need re-adjusting, and I think my clutch master is very tired and needs a rebuild. 
    • If you are keen, have a look at my build thread. Car is for sale for the right money or straight swap for a F80 M3 LCI.
    • Welcome mate.  No point in over thinking it, buying any one of those cars you mentioned is not a smart or logical choice with the availability of many "better" (re price to performance) cars available to you.  The heart wants what the heart wants, buy whatever it leads you too.
    • Hey everyone! Im so grateful to be apart of this community and ill do my best to be apart of this. Firstly, i'm not disclosing my real name due to in real life circumstances surrounding my privacy and public image (sorry lol) Secondly, The only thing personal I am willing to share is that I'm from Sydney and a descendant of one of Sydneys largest mortgage firms. I got gifted my first ever car, a 2022 Porsche Cayenne and I love it to death. Ive been driving it for about 5 or 6 months now and honestly Im so grateful for my parents for gifting me this vehicle. However recently I've been working my ass off to afford my second car (which I need help deciding soooooo community help me out please?). Once decided, im planning to try modify it myself. Recent I've been thinking about getting a Skyline, particularly a 25GT or GT-V, yes I know overrated as hell, but I'm also considering a Chaser which I recently came to love. However my dream is to one day own a 180SX (So hard to find clean versions and im not really into importing).  Lastly before I send this off, I want to apologize if I sound tacky or pretentious. I try not to and want to genuinely learn from everyone and anyone. (Im no expert in this area) Thanks for reading!
