MJP02 Posted February 25, 2016 Share Posted February 25, 2016 Hey all I have an 02 bug wrx, recently I've noticed when I've accelerated hard at high speeds my engine light flashes, the first few times it stopped when I slowed but yesterday it stayed on. I have got a reader so I plugged it in and it says misfire on 1 & 2 cylinders. It didn't feel like it was missing. I have got new plugs on order but is this a common thing? should I look at getting new coil packs to? Thanks for the advice Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted February 25, 2016 Share Posted February 25, 2016 Start with coils and plugs. Which plugs did you order? Quote Link to comment Share on other sites More sharing options...
MJP02 Posted February 25, 2016 Author Share Posted February 25, 2016 I ordered standard plugs so far NGK 3500 PFR6B - Double Platinum Spark Plugs Not long had the car, apart from a back box i think its totally standard, also ordered the cosworth filter and walbro fuel pump, serviced it with millers 10 60, new disc's and pads all round and new front callipers plus new eagle f1's all round Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted February 25, 2016 Share Posted February 25, 2016 Pfr6b are good plugs. Avoid the bkr plugs. They don't work so well under load and cause a misfire when boost blows them out. Quote Link to comment Share on other sites More sharing options...
MJP02 Posted March 1, 2016 Author Share Posted March 1, 2016 Ok swapped the plugs at the weekend, old ones looked in really good condition. So today was first time to test and now i can feel the car almost pulling back when at high speed. Should i get new standard coil packs or uprated ones.
