[NightShift]

OK so there are many of these and im very sry but have searched and purchased many parts to try and remedy my problem but it seems as nothing works
Car has Built block rebuilt head
gt2871r
550cc
fmic
3" exhaust
emance rom tuned
HAD an safc when removed car seemed to idle slightly better
alternator is good
good battery
ecu gave code 55

car has rough idle 850-1000rpms
AEM wideband reads 10 or (- -)
FPR is set at 40psi w/ va
black/grey unburnt fuel spewing out the exhaust when i go to feel the exhaust air it is pulsating and small black dots(unburnt fuel) appear on my hand.
when i unplug Z32 maf car idles better this is my second Z32 maf
originally had different maf connecter so i took that off and now dont know which white wire is the maf

i have B white to white (Says Primary?)
c black to chassis ground
d orange to harness ground
e black/white to other white wire with no writting?

thanks,
Keith

sry for a long post tried to give as many details as possible

Cliff: Pinpointed to maf problem could be bad wiring?

[NightShift]

coilpacks are good all getting spark and all look very even when i changed to new plugs
injectors are also good each changing idle when plug removed.

Problem finally corrected The original maf wiring (done by previous owner) was grounded to powersteering pump which has two rubber grommets behind it meaning that did nothing

so i moved this to chassis cleaned surface with sandpaper to bare metal then for shits and giggles put old maf wiring harness back on and BAM she started right up sounded mean as hell

so i took her out no hesitation to 10lbs. slight missing up top seems to go (11-13 at partial throttle) then from 15-17on wideband to completly lean when at idle BAD SPARK PLUGS im running bkr6e i know i need 7 or 8 but i wanted to make sure my plugs werent my original problem?

I tried 4 different emance tunes, all ran like crap. switched to the Nistune with the base tune from Pete at PLMS and it ran perfect. ditch the emance and it will run fine.

dont waste your money w/ emance, they are crapp!! go w/ something like JWT and enthalpy. they are well worth the money.
