NicsR33 Posted October 26, 2006 Share Posted October 26, 2006 i got the same problem after fitting the fmic and exhaust. it gets pretty bad on anything over 7psi. im gonna try this and hopefully this will solve it!!! (it sucks spending all thsi money and not been able to boost it more than 5psi ) Link to comment https://www.sau.com.au/forums/topic/119403-how-to-fix-missfire-problem/page/3/#findComment-2619503 Share on other sites More sharing options...
RESP33z Posted November 9, 2006 Share Posted November 9, 2006 How much time have you guys allowed for the silicone to settle? Did this on my mates skyline last night, yet to put them back in to try... He also had a white powder on the top of one of his plugs.. would this be related or could the problem be something else making him run lean? cheers Link to comment https://www.sau.com.au/forums/topic/119403-how-to-fix-missfire-problem/page/3/#findComment-2655399 Share on other sites More sharing options...
RESP33z Posted November 9, 2006 Share Posted November 9, 2006 Put the coils back in today, misfires more between 1000 and 2000 rpm now. anyone have any ideas on what may be causing it?

huddy Posted November 9, 2006 Share Posted November 9, 2006 isolate which cylinder is the problem if possible, then check plugs/gapping swap with another coilpack to see if its the coilpack and if it has an ignitor pack check that wiring and earth as last resort Link to comment https://www.sau.com.au/forums/topic/119403-how-to-fix-missfire-problem/page/3/#findComment-2658145 Share on other sites More sharing options...
SnipeR-33 Posted November 13, 2006 Share Posted November 13, 2006 Is it possible to use an S2 coilpack on an S1? Mine misfires around 4000 - 5000 rpm just a little though. boost is set on 10.5 psi. Not sure how to silicon an S1 coilpack so im thinking maybe use an S2, is this possible?

Nozila Posted November 14, 2006 Share Posted November 14, 2006 doubt series 2 can be used on series 1 simple because one has a built in ignitor whilst the other doesnt.

Rolls Posted November 14, 2006 Share Posted November 14, 2006 Ok Ive got splitfires and new connectors and mines still misfiring very slightly on cold nights. Mainly in 3rd but a bit in 2nd as well at around 5000-5500 after and before are fine. Any clues? ive gapped the plugs down to .6 and its an older redtop rb20det. Its gets quite rich about 10:1 once at around 5000rpm Link to comment https://www.sau.com.au/forums/topic/119403-how-to-fix-missfire-problem/page/3/#findComment-2670468 Share on other sites More sharing options...

RESP33z Posted November 15, 2006 Share Posted November 15, 2006 hey guys, we changed the spark plugs to ngk platinums heat grade 6 with a .9mm gap. before this it had ngk iridiums heat grade 5 with a 1.1mm gap. Also took the coils out again, took off all the silicone, put them in a metho bath for 15 minutes, blew them out with an air compressor, then put them in the oven at 80 degrees over night. Anyway put the car back together and no more misfiring but the car is running like 12psi!!! Only performance mods to the car are turbo back exhaust with high flow cat, and pod filter.. Just wondering if you guys reckon its just getting a better spark now? hence more boost pressure...(before it was struggling to get to 9psi) or do you think I may not have connected something properly. so far my mate is loving his car running 12 psi but after he has a bit of fun we are gonna try to find out why because we dont wanna blow anything. Anyway if you know which vacuum hose we may or may not have connected or connected properly that would make it do this let us know.. or if it is just the better spark then let it be... before 4500rpm it still limits to 6psi then shoots up to 12psi...which confuses me a bit..

mr_crust Posted November 16, 2006 Share Posted November 16, 2006 i had a misfire issue as well and i tired everything , but the fix for my car was the fuel filter..i went down to repco and got myself a new one , changed it over and i was running normal again. once the old fuel filter was out , i blew through it and blackish petrol came out of it , so a bad batch of fuel along the way caused it.

eXc Posted November 19, 2006 Share Posted November 19, 2006 I wanted to silicone mine, but can't find anywhere that stocks it in newcastle. Bunnings here doesn't have it. Any ideas?
