Intermitten Miss

[robwantsR32]

i've had this miss coming in and out for a few weeks and can't find the cause.

the miss like i said comes and goes, when it comes its jus like its not making much power. still pull but at about 1/3 the usual.

i've changed the plugs and checked the coils were sparking on each cylinder.

anyone got any idea's on what to check next?

try your ignitor that was my problem.

Is it only when on boost or completely random? Miss on boost has been covered many times and can be found by searching, most likely causes are old plugs, old coils, too rich.

Random is a pain in the arse, and you are in for a world of pain trying to track it down.

With the stock ecu mine would occasionally have a single miss at part throttle, usually when slowing down then going to accelerate again. Unsure what it was, only every blue moon would it do it.

PFC and Z32 AFM went in and I haven't seen it since.

mate intermittent misses always end up being coil packs you just got to get lucky and catch them!

i had all 6 coils go 1 at a time

Mine wasn't, swapped all 6 no change, i also swapped ignitor, ecu, rewired ecu to ignitor,swapped ignition loom, regrounded everything, swapped cas and afm, removed emanage, which also required swapping back to stock injectors.

In the end i got the shits and got an rb25. Problem solved

Had same problem, the answer for me was coils.

Hmm, missing, as fun as it is to search it out yourself, IMO, take it to get a tune and let someone do that for you... also, you get your car dyno'd and tuned at the same time
