What do they cost? 2 minutes ago, arronm said: Just buy the correct pre gapped plugs 0.9 is the "correct" gap but 0.7 people are recommending which I've not seen on the shelf. Anyway so far people have recommended: Gap plugs Flow test injectors (this is a last resort) Anything else? As everything is pretty new I'm feeling like it might be something more..

I saw a screw type plug gapper on ebay for over 200 usd. Just tap them for now and you'll be fine. 0.9 is only correct for a stock car. I had stock plugs blow out when I went over 12psi and 12:1 afr. I took them to 0.7 and it was sorted. Link to comment Share on other sites More sharing options...

Think back to the various things that are different with your car since it ran properly. One of those changes could be the culprit. Link to comment Share on other sites More sharing options...
rollex Member 682 Member For: 9y 10m 16d Gender: Male Location: Australia Posted 16/02/17 06:05 AM Author Share Posted 16/02/17 06:05 AM That's what threw me, I haven't touched the tune or components in almost ~8 months then it just started happening making me assume a coilpack failure. But after new plugs, coils no love, fixing the cover and ensuring the the ECU plugs were in correctly (it has been out before), replugging in all the injectors fixes the idle but introduces the on boost missfire. I've smelt petrol for a while now (I need to look at this as well) but as it was already there its probably not related to the miss. I'll try gapping the plugs first then work my way through the list. Cheers for the help guys. 1 Link to comment Share on other sites More sharing options...
