Hello fellow Skyline owners! I’ve had my car in the garage for 6 months now, during winter time. Before I put it off I had the car remapped. During the mapping session the car suffered from intermittent missfires on higher rpm. Then when I was done and started the car to drive home the car only ran on 5 cylinders. We did some fault searching, narrowed it down to cylinder 3. Then all of sudden after we swaped coilpack 3 & 1 around, it worked again. The coilpacks used at the time were Splitfires (5 years old). One of the things I wanted to do was to upgrade the ignition system, so I did. I Installed VR38 smart coils. Also swapped out the sparkplugs (ngk bcp7res) gapped at 0.7mm. This is when I found out that all of my old sparkplugs were very black and a bit wet. I originally thought this was a tuning or fuel realated issue since it was affecting all the of the cylinders. This week I started her up. after about 40 minutes of total running (idle) I removed to check my new plugs.. All the sparkplugs have what looks like fresh engine oil on them. The threads are clean, just on the base and half around the center electrode, just as the previous ones too had. Earlier sparkplugs i’ve had replaced has never looked like this and I find it odd that it’s like this on all the plugs. Do you guys have any ideas what would cause all the cylinders to have oil in them all of sudden? 🤔 Will upload a picture so you can see too. The car is a R33 RB25DET Car has uprated turbo,injectors,maf,ebc.. Running a apexi power fc. Unopend engine. Done about 90000km

SKYLINE WONT START ! HELP !! So hear me out first guys, hear the full story it might help !! i changed my Blitz Pod filter to a K&N one Car was running fine, and on my way back home I decided to give it abit in the tunnels, after giving it all the sudden my car started choking or chugging and I thought my engine died, but it was still running, it runs fine till I step on the pedal half way it chugs and struggles and pretty much wont let me Go over 3,000 RPM so I thought maybe it's the POD that's acting up the AFM cause it felt like it was the case. So the next day I changed it back to the Blitz that I originally had earlier on and went to drive it around and it was back to normal "woooooooo" and as I got close to home it did it again the chugging and choking like it was gonna die, so I was f.. could it be my spark plug or coils. So the next day I changed my Spark Plug, it was a BKR5EIX-11 which isn't recommended but I had it laying around so I replaced it, my old spark plug was black and burnt on the tip so I thought yeah maybe this should do the trick! Plug everything back in and.... it CRANKS AND STARTS FOR A SPLIT SECOND AND immediately dies out and I only have one conclusion left, the Coilpacks but I want to see what you guys think -every hose is plugged in correctly and tightly -strange thing is that before I change the spark plug the car was running but a weak start up so I thought Spark plug but now I don't even know anymore. PLEASE HELP ME GUYS !! Could it be the coilpacks ?? Could the spark plug have anything to do with it, even if it's not recommended it should still start up, it's gapped at 1.1 which is how the plugs came (Bkr5eix-11)

So i just changed my sparkplugs on my r34 everything was fine I drove it for like 10 minutes and then the engine light came on and then it started misfiring really bad, now on idle, it sounds like its running on fewer cylinders. I got engine fault code 21
