R32 Rb20Det Misfiring.

[benoss]

Hey guys, my r32 gts-t has been misfiring every now and again, it's starting to annoy me now because it's been doing it more often.

Some days it won't even do it once but others it'll do it 4 or 5 times in the one day.

I'll be driving along then it'll start misfiring out of no where and it sounds like a wrx hahaha. But if I just down shift and come back on boost it'll sort it's self out. I'm thinking it might be a faulty coil pack but in not 100% sure. Just wondering if anyone could help me out. Thanks!

Plugs?

Strange that it clears up on boost, it's usually the other way around.

It has splitfire coil packs as well, thanks man I'll get some new plugs for it tomorrow and put them in and see if that changes anything. But it's weird like as it comes back on boost within three seconds it'll fit it's self and won't do it again for like another 10-20 minutes. Sometimes it won't even do it again till the next time I drive it.

Might be a dirty/failing injector.

I'll put some new plugs in and if that doesn't sort it out I'll get the injectors cleaned.

Any suggestions on what plugs I should get for it?

Coppers NGK BCPR6ES

or

Platinum PFR6ES

in either case gap them down to 0.8mm

Thanks man!

I put new plugs in it the other day, it didn't misfire for about a week but it started again today. Didn't do it much but the plugs defiantly improved it

[benoss]

This is still happening, my r32 is fairly stock has a fmic, splitfire coilpacks and it's running 12psi boost on stock turbo. Could it be the injectors? When it starts misfiring I just rev it out to like 6k and it fixes it's self. Someone please help.

Sticky injectors could easily cause similar. You could get them cleaned and tested for around $25-$30, or just drop in some new ones...

Have you tried dropping the boost to 9 or 10 with some new plugs?

My bet is the igniter pack the small box at the back of the coil cover. Mine did the same but more or less on boost

[benoss]

It doesn't have a boost t so I can't wind the boost down to 10 psi can't I?

I've replaced the plugs already, but I'll get the injectors tested and cleaned next. Thanks heaps!
