mk5 gti serious misfire
« on: January 25, 2013, 09:05:44 pm »
hi just done k04 conversion with s3 injectors. got the stage 3 map but got serious misfire on cylinder 4. changed plugs and coils. still got it. car will drive fine on partial load but will misfire bad when wot. going to change the injector tommorrow to hopefully sort it. is there anything else i can try while the manifold is of.

ps.
i had like 50 misfires within a couple of seconds on vagcom. is it very likely that it is a faulty injector

Exactly what I had when I went K04, misfire on high boost.
New injector fixed it.
