Rb25 Misfire

[fmlycar]

I have a stagea with a s2 rb25. Mods are power fc, nismo 550cc, z32 afm, td06, splitfire and usual bolt ons.

Has developed a miss under load (approx half throttle) and when approaching boost. Is constant miss right through the Rev range when trying to boost and feels very hesitant. Can see the guage trying to comes up, stutters and hesitates, then starts boosting but missing all the way through the revs.

I swapped the plugs (bpr7es) for some spares I had in the shed. Was dark when I swapped them so didn't get a good look at the coil packs but I think they are fine. Didn't make any difference.

Checked afm voltage with car off 0.42v, running at idle is 1.5v and cruise is 1.72v.

Sprayed all vac hoses with brake cleaner with no change to idle. Found a single hose clamp under air filter was loose and tightened that. Still no difference.

Any suggestions?

Free revs under light throttle fine, heavy throttle it misses and splutters heavily. Idles without fault also

I didn't think that one worked. It came up with an error when I tried to post it
