R32 Misfiring big time

[Bazelinez]

hey guys,

my car has been going bonkers today. When I rev it around 4K at WOT on 12PSI its spluttering and backfiring and there seems to a chime coming from under the dash?! Like a door open chime? Its bizarre. It comes and goes. One minute its clean and the next its dying....It won't accellerate at all. It feels like a cut almost but the boost isn't high enough...

Anyone got any ideas?

Righto, just seen the sticky at the top. I'll try and wrap them tomorrow still don't have any idea what the chime is though?!

What's a set of Splitfire coil packs worth these days? Anyone got a second hand set around?

I had a bad backfiring/missing problem on my 32 GTR. Changed the air flow meters and it was perfect.

Took my coils put today and 3 were split on the greay part surrounding the metal thing. Very technical eh? Taped them up but in thr process I noticed a shitload of green calcium build up and general crud up inside.

I took a Dremel (small high speed drill thingy) and lightly ground the inside of each coil pack until it was shiny again. I already had new springs inside and I screwed a tiny allen bolt up the guts of each spring to replicate the factory set up.

In all I had about 3 teaspoons of carbon/calcium/crud I removed from all the coilpacks.

Result is fixed mis firing, stronger performance, better idle. Worth the effort if you have the tools.
