Issues With Ingition Or Spark, Misfiring?

[HR31-PASSAGE]

hey guys i'm having some issues with my ignition? it seems its not getting constant spark to the coilpacks on my rb25.

i've changed the ignition switch on the back of the barrel thinking that was the issue but the car started & ran fine till i drove out the drive way & started misfiring.

anyways is there anything else i can check to solve the issue?

replace ur sparkplugs.

sparkplugs when there on there way out do strange things. so first thing i would do is replace them because its probs the easiest and cheapest thing to replace

plugs are new, changed the AFM & CAS but still done it.

its acts like when you take the plug off the afm doesn't know what to do & runs shit or a boost leak but i've checked everything.

when is the misfiring happening??? its common that misfire happens on either full boost or at high rpm and thats when the coilpacks are starting to show that they need replacing.

all the time pretty much but when the car goes to idle it just stalls but if i keep the revs up like 1500-1700rpm it ok but i can still hear some kind of miss like its not sparking all the time...

i have changed the coils to after market ones & stock ones...

ahhh ok ok, it could also be the coil pack wiring harness.

Have you worked out which coil is misfiring?

Is it a S1 or S2 RB25? If it's a S1, then it could be a failing ignitor module.
