well during this hot weather an intermittent missfire has shown its head. Its not just an on boost thing, when its missing its idle and on throttle and all except it sounds normal only on deceleration. power is down offcourse when its on sounds like a wrx well and truly
thing is car will be fine after start then driving well with full power, then get stuck in traffic for 5-10 mins and its gone into complete missing mode - so basically it is on off and seems to be when very hot
now i know most common to look for this kinda thing is spark plugs and coils, i replaced spark plugs a few days ago (bcpr6es) i think 1mm gap but b4 it was doing it with the stock plugs which seemed like a bigger gap like 1.1 or 1.2
any ideas guys?? can the coils or any other item fail when really hot??
