Missfire When Warm

[Michaelove]

I have changed my spark plugs, gepped to .08, siliconed my coil packs and all that and I still get a miss fire every once in a while when my car is warm. Is there anything else I could do to stop this? My power fc is coming in tomorrow, will that fix it? It's nothing bit, it just bothers me.

not always does the siliocn trick work so its probably still your coil packs. (did it on friends r34 twice and it failed so bought spitfires)

either try siliconing it again or purchase some aftermarket coilpacks

I had the same problem with my car (RB20DET) and i innitially thought it was the ignigtor overheating. Like you it only happened when the car was warm. But after putting my car on a scan tool at Nissan and coming up with no errors it was narrowed down to a module that even the scan tool can't pic up, which turned out to be the coilpacks. They were 15+yo after all. So i bought some splitfires off Sliding Performance off this site (link below) and chucked in some new plugs while i was there (old ones had done about 10,000km) and problem solved. The coilpacks were $485 delivered and took around 5 days to arrive. Hope this helps. Good luck.

Yeah, I tried the silicone job on mine - fixed it for a little bit (might just be the placebo effect), but then back to it's old ways. Replaced them with some younger coils and it's happy again! I'd ask someone if you can use their coils as a test, just to be sure it's not something else.

so younger OEM coils can fix this problem aswell? spitfires aren't REQUIRED?

generally age would make a difference, as older coils would be more liable to causing missfire. if you can find cheap oem coilpacks then it's worth the try.

People tend to go splitfires as you can get a whole set of brand new coils for the less than the price of two new OEM coils..
